• Locate and describe the major organs of the musculoskeletal system and their functions. and This arrangement of three bands of muscles in different orientations allows various movements and rotations of the trunk. The deep muscle, the transversus abdominis, is arranged transversely around the abdomen, similar to the front of a belt on a pair of pants. Table The diaphragm has three openings for the passage of the inferior vena cava, the esophagus and the aorta. Each muscle fiber (cell) is covered by The physicians originally studying human anatomy thought the skull looked like an apple. : pelvic muscle that resists intra-abdominal pressure and supports the pelvic viscera, linea alba : muscle of the spinalis group associated with the thoracic region, splenius ). : muscles that span the spaces between the ribs, internal intercostal The 11 pairs of internal intercostal muscles, just under the externals, are used for expiration because they draw the ribs together to constrict the rib cage. Parallel muscles have fascicles that are arranged in the same direction as the long axis of the muscle (  (Muscular System), Google slides adapted from the OpenStax A&P collection, a (Hank Green describes how muscles work), Ha`awina 13: Ke Kahu o nā `I`o : muscle deep to the gluteus maximus on the lateral surface of the thigh that laterally rotates the femur at the hip, patellar ligament PTs have a master’s degree or doctorate, and are highly trained experts in the mechanics of body movements. : superficial abdominal muscle with fascicles that extend inferiorly and medially, iliococcygeus : muscle that moves the mandible from side to side, longissimus capitis : (also, musculotendinous cuff) the circle of tendons around the shoulder joint, serratus anterior The three long muscles on the back of the knee are the hamstring group, which flexes the knee. axial Although the tongue is obviously important for tasting food, it is also necessary for mastication, deglutition (swallowing), and speech (. The bone connection is why this muscle tissue is called skeletal muscle. : muscle that inserts into the first metacarpal, anconeus : muscle located on the lateral surface of the tibia, tibialis posterior The external oblique, closest to the surface, extend inferiorly and medially, in the direction of sliding one’s four fingers into pants pockets. This muscle also creates skeletal muscle sphincters at the urethra and anus. : muscle that flexes the big toe, gastrocnemius : muscle that extends the hand at the wrist and the phalanges, extensor indicis  supinator : muscle that adducts the thumb, abductor pollicis brevis ). In other words, there is a muscle on the forehead (frontalis) and one on the back of the head (occipitalis), but there is no muscle across the top of the head. Because it is so moveable, the tongue facilitates complex speech patterns and sounds. Each muscle is segmented by three transverse bands of collagen fibers called the tendinous intersections. Suprahyoid muscles are superior to it, and the infrahyoid muscles are located inferiorly. : quadricep muscle that is between the vastus lateralis and vastus medialis and is deep to the rectus femoris, vastus lateralis The hypothenar muscles include the abductor digiti minimi, flexor digiti minimi brevis, and the opponens digiti minimi. : muscle of the lumbar region that helps extend and laterally flex the vertebral column, mylohyoid The rectus femoris is on the anterior aspect of the thigh, the vastus lateralis is on the lateral aspect of the thigh, the vastus medialis is on the medial aspect of the thigh, and the vastus intermedius is between the vastus lateralis and vastus medialis and deep to the rectus femoris. The palm is the origin of the intrinsic muscles of the hand. A synergist can also be a fixator that stabilizes the bone that is the attachment for the prime mover’s origin. : end of a skeletal muscle that is attached to another structure (usually a bone) in a fixed position, parallel : group of muscles on the medial aspect of the palm, hypothenar eminence Suprahyoid muscles are superior to it, and the infrahyoid muscles are located inferiorly. When a parallel muscle has a central, large belly that is spindle-shaped, meaning it tapers as it extends to its origin and insertion, it sometimes is called Define each medical term. : posterior neck muscles; includes the splenius capitis and splenius cervicis, splenius capitis : four-layered group of intrinsic foot muscles, plantaris , muscles that move the arm, muscles that move the forearm, and muscles that move the wrists, hands, and fingers. ). : medially placed muscles of the erector spinae, spinalis thoracis The plantaris runs obliquely between the two; some people may have two of these muscles, whereas no plantaris is observed in about seven percent of other cadaver dissections. : quadricep muscle on the medial aspect of the thigh.

If you injured your shoulder while you were kayaking, the first thing a physical therapist would do during your first visit is to assess the functionality of the joint. The three layers of muscle also help to protect the internal abdominal organs in an area where there is no bone. There are four pairs of abdominal muscles that cover the anterior and lateral abdominal region and meet at the anterior midline. : muscle deep to the gluteus maximus on the lateral surface of the thigh that laterally rotates the femur at the hip, obturator internus Because it is so moveable, the tongue facilitates complex speech patterns and sounds. The pectoralis major is thick and fan-shaped, covering much of the superior portion of the.

Surgical Procedures of the Musculoskeletal System: Terminology The musculoskeletal system is composed of many parts, including the muscles, tendons, and fascia. Patients with diseases of skeletal and muscular system, circulatory system, and tumor made up 90.48% of the population, indicating that the diagnosis as well as treatment of those disease categories cost much more higher than that of other disease categories, which meant diagnosing and treating these diseases were more difficult and called for advanced medical technologies in the process. The adductor longus, adductor brevis, and adductor magnus can both medially and laterally rotate the thigh depending on the placement of the foot.
