List of skeletal muscles of the human body - Wikipedi

  1. This is a table of skeletal muscles of the human anatomy.. There are around 640 skeletal muscles within the typical human body. Almost every muscle constitutes one part of a pair of identical bilateral muscles, found on both sides, resulting in approximately 320 pairs of muscles, as presented in this article. Nevertheless, the exact number is difficult to define because different sources group.
  2. al arises as fleshy fibers, from the lateral third of the inguinal ligament, from the anterior three-fourths of the inner lip of the iliac crest, from the inner surfaces of the cartilages of the lower six ribs, interdigitating with the diaphragm, and from the thoracolumbar fascia
  3. is (External or descending oblique muscle) (Fig. 392), situated on the lateral and anterior parts of the abdomen, is the largest and the most superficial of the three flat muscles in this region. It is broad, thin, and irregularly quadrilateral, its muscular portion occupying the side, its aponeurosis the anterior.
  4. The fibers are in the inferomedial direction. Hands on tits - sorry for being crude, but that's the mnemonic - 'hands on tits', they're up in that direction, so the fibers pass superiorly and medially. 'Tits' has an 'i' in it, so 'internal' oblique. The fibers are superomedial
  5. al muscle its fibers run inferomedially, unilateral action results in ipsilateral side flexion and contralateral rotation of the trunk bilateral action to flex the vertebral column by drawing the pubis towards the xiphoid process
  6. is is the large muscle in the mid-section of the abdomen. It enables the tilt of the pelvis and the curvature of the lower spine. Next to it on both sides of the body is the.
  7. The posterior scalene muscles, located on the lower sides of the neck, ipsilaterally bend the neck to the side and elevate the second rib. The splenius capitis and splenius cervicis also assist in neck side bending. The erector spinae muscles (iliocostalis, longissimus, and spinalis) are large, deep muscles that extend the length of the back. All three act to ipsilaterally side bend the neck

A muscle that is acting as a synergist during a joint action may do which of the following?-Stablilize a joint to restrict undesirable movements of a bone-Relax to give the primer mover complete control over the action-modify the direction of the movement produced by the prime mover-contract together with the prime mover to produce more powe Sternocleinomastoid. These muscles elevate the ribs and have their origin on the inferior border of the superior rib and their insertion on the superior border of the inferior rib. External intercostals. When contracted, this muscle causes expansion of the thoracic cavity and increases pressure in the abdominopelvic cavity The anterior abdominal muscles (rectus abdominis, ecternal and internal obliques, and transversus abdominis) form a natural girdle that reinforces the body trunk; the paired straplike rectus abdominis muscles are the most superficial muscles of the abdomen; the external oblique muscles are paired superficial muscles that make up the lateral walls of the abdomen; the internal oblique muscles are paired muscles deep to the external obliques; and the transversus abdominis is the deepest. The muscles that affect the knee's movement run along the thigh and calf. They are attached to the femur (thighbone), tibia (shinbone), and fibula (calf bone) by fibrous tissues called ligaments Sandro Palla, in Functional Occlusion in Restorative Dentistry and Prosthodontics, 2016. Articular Disk and Lateral Pterygoid Muscle. The relation between the disk and the superior head of the lateral pterygoid muscle has been the focus of several investigations because dysfunction of the superior head has been implicated in the etiology of an anterior disk displacement

The Muscles and Fasciæ of the Abdomen - Human Anatom

Mimetic muscles have several characteristics that differentiate them from skeletal muscles. Generally, mimetic muscles have their origin in bone and insert on the skin and among the fibers of other muscles, with no tendons, except for the sphincteric muscles [].In addition, mimetic muscles appear to lack typical muscle spindles [17, 18], which function in resetting resting tone Muscle Name Origin Insertion Action Innervation Muscles of Upper Extremity Pectoralis Major Medial half of clavicle, front of sternum, costal cartilage Crest of greater tubercle (Lateral lip of bicipital groove) Horizontally adduct, medially rotate at shoulder Medical and lateral pectora Biceps brachii is one of the three muscles found in the anterior compartment of the arm. It gets its name from its two heads, each of which has a separate origin. The long head originates from the supraglenoid tubercle of scapula, while the short head shares its origin with the coracobrachialis muscle at the coracoid process of scapula.. The muscle fibers from both heads converge to a single. The latissimus dorsi (/ l ə ˈ t ɪ s ɪ m ə s ˈ d ɔːr s aɪ /) is a large, flat muscle on the back that stretches to the sides, behind the arm, and is partly covered by the trapezius on the back near the midline. The word latissimus dorsi (plural: latissimi dorsi) comes from Latin and means broadest [muscle] of the back, from latissimus (Latin: broadest)' and dorsum (Latin: back) The lower island trapezius myocutaneous flap is applicable to the reconstruction of defects of the neck, face, oral cavity, and lateral skull. An osteomyocutaneous flap was described by Dufresne and colleagues. 124 The most useful bone for composite transfer is the spine of the scapula. 125 The muscle has distinct fiber orientation in three.

  2. This muscle can be worked out in 2 different ways: by either bringing the chest towards the pelvis (as with a crunch), or by bringing the pelvis towards the chest (as with a leg raise). This is what people mean when they say they're working their 'upper' or 'lower' abs
  3. g a zig-zag oblique line on the lateral side of thorax. From here, the muscle fibers fan out towards the midline and inferior margins of abdomen; the most posterior fibers course almost vertically, while the remainder passes anteromedially
  4. The slanting direction refers to the direction of the fibers of this muscle. The fiber direction of the internal obliques is in the direction of reaching across your body. As in, if you place your hand on the opposite side of your abdomen, your fingers represent the direction of the fibers. External obliques. The name external obliques also refers to the location and shape of the muscle
  5. al wall. The vertical muscles aid in compressing the abdo

Human skeletal muscle is composed of a heterogenous collection of muscle fiber types. 1- 3 This range of muscle fiber types allows for the wide variety of capabilities that human muscles display. In addition, muscle fibers can adapt to changing demands by changing size or fiber type composition The external oblique muscles are the outermost fibers of the trunk, and are located on each side of the rectus abdominis. Their upper and lateral attachments are to the lower eight ribs by tendinous insertions that interdigitate (interlock like the fingers of folded hands) with the serratus anterior muscle on the side of the rib cage Muscle Fascia Fascia is thickened connective tissue that envelops a muscle or a group of muscles. Superficial fascia is found directly under the skin. Epimysium is the fascia closest to the muscle. Perimysium divides the muscle into facicles - muscle fibers. Endomysium is another type of connective tissue that covers each muscle fiber With fibers fanning out as it approaches the femur, it is larger than the brevis. This muscle also finds its origins on the superior ramus of the pubis, and it attaches to the femur farther down the bone than the pectineus and adductor brevis, inserting along the linea aspera about midway down the shaft

Skeletal muscle fibers that contract slowly and that cannot propagate an action potential along their cell membranes. Tonic muscles are uncommon in humans and are found only in the extraocular muscles, stapedius muscle, and intrafusal fibers of the muscle spindles. The remainder of human skeletal muscle contains only twitch fibers 4d. The Muscles of the Mouth - Human Anatomy. The Quadratus labii superioris is a broad sheet, the origin of which extends from the side of the nose to the zygomatic bone. Its medial fibers form the angular head, which arises by a pointed extremity from the upper part of the frontal process of the maxilla and passing obliquely downward and lateralward divides into two slips Muscle Definition. A muscle is a group of muscle tissues which contract together to produce a force. A muscle consists of fibers of muscle cells surrounded by protective tissue, bundled together many more fibers, all surrounded in a thick protective tissue.A muscle uses ATP to contract and shorten, producing a force on the objects it is connected to

  4. This is the picture of a fusiform muscle, which is in fact, the most populous type of muscle in the body. Fusiform muscles tend to be long and thin attaching at sometimes distant points. They most often cross hinge joints and since they offer only one direction of pull or movement, assisting mainly in flexion and extension

Constricting clothes or girdles, tool belts, and seat belts can extrinsically compress the nerve. A protuberant abdomen may compress the nerve against the inguinal ligament, accounting for symptoms in the obese and in women in late pregnancy. The sartorius muscle may compress the nerve in dancers when the leg is in the turned out position The term is used both generically to describe the action of any muscle that moves away from the midline (the gluteus medius, for example, is an abductor in that its action is to pull the thigh out from the midline) and as part of the formal name of a handful of muscles such as the abductor pollicis brevis, which pulls the thumb away from the palm As with all muscles, the direction of the muscle's line of pull determines the muscle's action, and the direction of the muscle's fibers essentially determines the line of pull. Muscles of the neck that perform flexion, extension, right lateral flexion, and/or left lateral flexion must have a vertical component to their fiber direction Middle fibers retract the scapula; Upper and lower fibers rotate the scapula forwards; Latissimus Dorsi: The latissimus dorsi a large, flat muscle on the back and, behind the arm, and is notably covered by the trapezius on the back near the midline. The latissimus dorsi is the longest muscle in the upper body

A muscle twitch is an involuntary contraction of the fibers that make up a muscle. Nerves control muscle fibers. When something stimulates or damages a nerve, it causes the muscle fibers to. The pretarsal orbicularis muscle fibers join together along the surface of the lateral canthal tendon and the lateral horizontal raphé. Additional bundles of thin muscle fibers run along the upper and lower eyelid margins. These are referred to as muscles of Riolan. These are firmly fixated to the tarsus

The internal oblique is a muscle that is deep to the external oblique and has fibers that crisscross those of the external oblique. Its actions are similar to those of the external oblique Finally, the direction in which the muscle fibers run can be used to identify a muscle. In the abdominal region, there are several sets of wide, flat muscles. The muscles whose fibers run straight up and down are the rectus abdominis , the ones running transversely (left to right) are the transverse abdominis, and the ones running at an angle.

The muscle fibers pass in a superomedial direction. Laterally, it is muscular and medially it forms an aponeurosis that merges into the linea alba at the midline 2 . The internal oblique muscle has a free lower border, in comparison to the external oblique muscle that has a free posterior border which forms the anterior boundary of the lumbar. It arises from the lower third of the lateral supracondylar ridge of the humerus, from the lateral intermuscular septum, and by a few fibers from the common tendon of origin of the Extensor muscles of the forearm. The fibers end at the upper third of the forearm in a flat tendon, which runs along the lateral border of the radius, beneath the Abductor pollicis longus and Extensor pollicis brevis; it then passes beneath the dorsal carpal ligament, where it lies in a groove on the back of the. Teres Minor is one of the four rotator cuff muscles surrounding the shoulder. Its main action, along with Infraspinatus is to externally rotate the shoulder joint. There are two Teres muscles, the other being Teres Major. Origin: Midsection of the lateral border of the scapula. Insertion: Greater tuberosity on the humerus. Actions: External rotation The superficial inguinal ring is formed by an opening in the aponeurosis of the external abdominal oblique muscle, with the base at the pubic crest and a lateral and medial crus dividing and fusing.. Lateral Compartment . The lateral compartment is along the outside of the lower leg. It contains the peroneus longus and peroneus brevis muscles. These muscles pull the toes and feet outward. They also help with pointing the foot, or plantarflexion. To feel these muscles contract, place your hand on the outside of your shin and turn your foot out

  1. Throughout the rest of the GI tract, the inner circular muscle layer has smooth muscle fibers lying in a concentric fashion around the circumference of the GI tract, while the outer longitudinal muscle layer has fibers orientated parallel to the direction of the GI tract. (Note that in the stomach there is also an additional innermost oblique.
  2. The lateral region assists in shoulder flexion when the shoulder is rotating, although it also assists the transverse abduction of the shoulder. The posterior region is the hyperextensor of the shoulder, contributing to transverse extension. Teres Major: The teres major is a thick flattened muscle connecting the lower scapula with the humerus
  3. Pectoralis major: This muscle has two heads, or sections of muscle tissue, and covers much of the front of the thoracic cage. The clavicular head attaches to the medial portion of the clavicle.

The deltoid muscle is shaped like an inverted triangle. It can be divided into an anterior, middle and posterior part. Attachments: Originate from the lateral third of the clavicle, the acromion and the spine of the scapula. It attaches to the deltoid tuberosity on the lateral aspect of the humerus. Innervation: Axillary nerve. Actions These tissues include skeletal muscle cells (called muscle fibers), blood vessels, nerve fibers, and connective tissue. Each skeletal muscle has three layers of connective tissue that enclose it, provide structure to the muscle as a whole, and also compartmentalize the muscle fibers within and around other muscles (Figure 4.3) A muscle strain in the lower left back occurs when the muscle fibers overstretch, leading to inflammation. In addition to pain in the lower back, symptoms may include: a limited range of motio Since the weak muscle is unable to bring the eye to a position in which the object is focused on the macula, the image falls on a more peripheral part of the retina. The person sees the object in the field appropriate to the new retinal position (i.e., always farther toward the periphery in the direction of attempted gaze)

Each lumbrical has usually the same innervation as its deep tendon, i.e., the first two from the median and the last two from the ulnar. The lumbricals are inserted into the lateral (radial) sides of the extensor expansions of fingers 2 to 5, and they are chiefly extensors at the interphalangeal joints. Variations in attachments are common Anatomy. The pec t oralis major is a relatively large, fusiform (within each region), and heavily-segmented muscle that originates on (1) the medial half of the clavicle, (2) the lateral side of. It's quite small. The lateral pterygoid muscle arises partly from the underside of the greater wing of the sphenoid, and partly from the lateral aspect of the lateral pterygoid plate. The fibers of the lateral pterygoid muscle run backward and a little laterally. We'll go round to a medial view to see where they go. The main insertion of. The rapid development of interventional procedures for the treatment of arrhythmias in humans, especially the use of catheter ablation techniques, has renewed interest in cardiac anatomy. Although the substrates of atrial fibrillation (AF), its initiation and maintenance, remain to be fully elucidated, catheter ablation in the left atrium (LA) has become a common therapeutic option for.

The uppermost fibers insert into the lower five ribs and their cartilages (Fig. 45-3; see Fig. 45-2A). The central fibers form an aponeurosis at the semilunar line, which, above the semicircular line (of Douglas), is divided into. ribs 9-12, lateral to the angles: pulls down lower ribs: branches of the ventral primary rami of spinal nerves T9-T12: lowest posterior intercostal a., subcostal a., first two lumbar aa. a respiratory muscle, it receives ventral ramus innervation; embryonically related to the intercostal muscles, not the deep back mm. serratus posterior superio The inferior oblique muscle originates from the maxillary bone behind the lacrimal fossa, slightly posterior to the orbital rim. It passes posteriorly and laterally in the orbit, forming an angle of 51º with the visual axis of the eye in primary position, before passing beneath the inferior rectus muscle and inserting posterior to the equator on the inferior and lateral aspect of the globe

9. Locate the external and internal oblique muscles. The external obliques lie lateral to the rectus abdominis muscles, (Figure 1.7) and sweep downward and medially from the bony part of the lower ribs to the pelvic bone. Their fibers run in the same direction as the fibers of the external intercostal muscles The orbicularis oris is a circular muscle that moves the lips, and the orbicularis oculi is a circular muscle that closes the eye. The occipitofrontalis muscle moves up the scalp and eyebrows. The muscle has a frontal belly and an occipital (near the occipital bone on the posterior part of the skull) belly. In other words, there is a muscle on the forehead (frontalis) and one on the back of. Pain in your lower legs may be due to issues with nerves, blood clots, or a number of other potential problems.

The nervous system of the abdomen, lower back, and pelvis contains many important nerve conduits that service this region of the body as well as the lower limbs. This section of the nervous system features the most inferior portion of the spinal cord along with many major nerves, plexuses, and ganglia that serve the vital organs of the. During dissections of the transversus abdominis, some defects were found in 14 out of 60 muscles and aponeurosis studied (23.3%) and the width of the Spigelian aponeurosis ranged from 1.5 to 3.5. The abdomen constitutes the part of the body between the thorax and pelvis, in humans. Most people don't know much about abdominal muscles except how to make abs. as a medical practitioner you are expected to know these muscles and how to treat any anomaly in them. Take the quiz below aimed at helping you in the exam The rectus abdominis has been removed, as have the external obliques.] Some of the muscle fibers interdigitate (fit together like clasped fingers) with the diaphragm and the transversus thoracis (see internal intercostals) Unlike the other abdominal muscles, the transversus abdominis are not postural muscles. They are very important in respiration, and are probably instrumental in forced exhalation The external oblique muscle is one of the outermost abdominal muscles, extending from the lower half of the ribs around and down to the pelvis. Its lowest part connects to the the top corner of the pelvis (called the crest of the ilium), the bottom-front of the pelvis (the pubis), and the linea alba, a band of fibers that runs vertically along the inside of the abdominal wall

There is breast tissue (arrow) that extends along the lateral margin of the pectoralis major (P) that must be pulled into the field of view on a mammogram. The same tissue was excised from. The SCM muscle is of interest to anatomists because the unique position it occupies in the neck makes it key to understanding the layout of cervical muscles. On either side, the SCM diagonally divides the neck musculature into anterior (front) and posterior (back) triangles, making the cervical spine easier to study A number of muscles help make up the walls of the cavity - the lateral walls include the obturator internus and the pirformis muscle, with the latter also forming the posterior wall In this article, we shall look at the anatomy of the muscles that make up the inferior lining of the cavity; the pelvic floor muscles Innervation of all the muscles of mastication (e.g., masseter muscle) and the suprahyoid muscles by the motor fibers; Supply of the teeth (lower molar, incisor, and canine teeth), the gums of the lower jaw, the buccal mucosa, the dorsum of the tongue, and the external acoustic meatus, including the eardrum, by the sensory fibers; CN VI. It assists in adduction. The lower fibers can create extension from a flexed position if there is a resistance to movement. Because of this last muscle movement, the pectoralis major could be seen to be an antagonist to itself. Postures where the pectoralis major muscle contracts

There are three flat skeletal muscles in the antero-lateral wall of the abdomen. The external oblique, closest to the surface, extend inferiorly and medially, in the direction of sliding one's four fingers into pants pockets.Perpendicular to it is the intermediate internal oblique, extending superiorly and medially, the direction the thumbs usually go when the other fingers are in the pants.

This can occur in any part of the body where there is a strain. However, muscle strain from coughing is mainly seen on the chest muscles and abdominal muscles. You can also get a pulled muscle in back from coughing. Constant and severe cough can cause the muscles to strain very badly and sometimes the muscle fibers even develop minor tears For example, information related to the lower part of the body travels in fibers located medially in the white matter of the spinal cord while those from the upper part of the body travel in fibers located at the lateral parts. Thus, the pathway is said to have somatotopic or spatial orientation

MRI OF MUSCLE INJURIES Robert Downey Boutin, M.D. Medical Director, Med-Tel International Skeletal muscle is the single largest tissue in the body, making up 25-50% of one's total body weight. As radiologists, we image many of the body's 434 muscles each day -- both intentionally and incidentally. Whe Muscle spasm or tightness causing coccyx pain. A possible factor in persistent coccydynia is muscle dysfunction. It is common to find taut bands that are very painful when pressed. Taut bands are strongly contracted muscle fibers within an otherwise relatively normal muscle The muscle hematoma can be the consequence of an impact against an external blunt or against a bone (direct trauma) or of a excessive or uncoordinated contraction (indirect trauma ) (Fig 1).In a direct trauma, when the muscle is contracted, the contusion will impact more superficial tissues while, in a relaxed muscle, the structural damage and the consequent hematoma, generally occur in depth. Type I - Red muscle is mostly made up of Type I fibers and is darker, respond slowly and have long latency, and are responsible for maintaining posture. These are long, slow contractions. Type II fibers - White muscles contain mostly Type II fibers and are responsible for fine and skilled movements. They have short twitch durations

The human gluteus maximus is a distinctive muscle in terms of size, anatomy and function compared to apes and other non-human primates. Here we employ electromyographic and kinematic analyses of human subjects to test the hypothesis that the human gluteus maximus plays a more important role in running than walking. The results indicate that the gluteus maximus is mostly quiescent with low. Each muscle has two tendinous origins. A medial head arises from the anterior surface of the pubic symphysis, whereas the larger lateral head originates from the upper border of the pubic crest, and together they form a muscle mass that inserts onto the fifth to seventh costal cartilages . The aponeuroses of the internal and external oblique.

A skeletal muscle is defined as multiple bundles of cells connected, which is known as muscle fibers, surrounded by connective tissue layers called 'fasciae.' There are three major muscle types, the others being.. The only exception was the retractor anguli oculi lateralis muscle (RAOL). RAOL was highly variable in size and presence —present in most of the gray wolves but typically more gracile than in the domestic dog, consisting of scant bundles of muscle fibers.

It is a complex movement of the whole body to generate power to a golf ball to propel the ball great distances with accuracy. This movement relies on the coordinated sequence of muscle activation to produce a fluid and reproducible movement. This paper reviews the literature on golf swing related muscle. Anatomy The rectus abdominis muscle is one of the anterior abdominal wall muscles, which together act to keep the viscera in place. Contraction aids expiration as well as evacuation of the rectum, bladder and uterus. It is a sheet-like muscle that is supplied by the ventral rami of the lower six or seven thoracic nerves. Normally the muscle.

The strengthening of thigh muscles is quite simple and you can just strength thigh muscles by going up and down the stairs. Another simple way to do this is sitting on the chairs frequently. Sitting in and getting out of the chair again and again will make quadriceps muscles much stronger The motor unit is composed of the motor neuron, its axon and the muscle fibers it innervates. Smaller motor neurons typically innervate smaller muscle fibers. Motor neurons can innervate any number of muscle fibers, but each fiber is only innervated by one motor neuron. When the motor neuron fires, all of its muscle fibers contract MUSCLES, TENDONS AND WILL Our Anatomy Gluteus minimus (p. 216) A small muscle originating just anterior to gluteus medius and inserting on the anterior aspect of the greater trochanter Its action is similar to that of the anterior fibers of the gluteus medius, but weaker if the iliac is fixed: flexion, abduction and medial rotation of the thigh. The other muscle is the superior tarsal muscle (of Müller) which is smooth muscle (innervated by postganglionic sympathetic fibers from the superior cervical ganglion) that can be seen in this section just above the tendon of the levator palpebrae at the fornix. If you trace the course of the smooth muscle fibers, you'll see that they follow.
