muscular system medical terminology

Along with the adductor longus, adductor brevis, adductor magnus, and pectineus, the strap-like gracilis adducts the thigh in addition to flexing the leg at the knee. Interactions of Skeletal Muscles in the Body, Although a number of muscles may be involved in an action, the principal muscle involved is called the prime mover, or agonist. Along with the adductor longus, adductor brevis, adductor magnus, and pectineus, the strap-like gracilis adducts the thigh in addition to flexing the leg at the knee. The first grouping of the axial muscles you will review includes the muscles of the head and neck, then you will review the muscles of the vertebral column, and finally you will review the : end of a skeletal muscle that is attached to the structure (usually a bone) that is moved when the muscle contracts, multipennate . Steps to Deciphering Medical Terms The steps used to read medical terms are: Start with and define the suffix. : move away from midline in the sagittal plane, : (also, prime mover) muscle whose contraction is responsible for producing a particular motion, : muscle that opposes the action of an agonist, : pennate muscle that has fascicles that are located on both sides of the tendon, : (also, sphincter) fascicles that are concentrically arranged around an opening, : fascicles that extend over a broad area and converge on a common attachment site, ; muscle fibers bundled by perimysium into a unit, : synergist that assists an agonist by preventing or reducing movement at another joint, thereby stabilizing the origin of the agonist, : movement that decreases the angle of a joint, : muscle that has fascicles that are spindle-shaped to create large bellies, : end of a skeletal muscle that is attached to the structure (usually a bone) that is moved when the muscle contracts, : pennate muscle that has a tendon branching within it, : end of a skeletal muscle that is attached to another structure (usually a bone) in a fixed position, : fascicles that extend in the same direction as the long axis of the muscle, : fascicles that are arranged differently based on their angles to the tendon, : (also, agonist) principle muscle involved in an action, : muscle whose contraction helps a prime mover in an action, : pennate muscle that has fascicles located on one side of the tendon, : a muscle anterior to the middle scalene, : muscle that has anterior and posterior bellies and elevates the hyoid bone and larynx when one swallows; it also depresses the mandible, ) flat broad tendon that connects the frontalis and occipitalis, : large muscle mass of the back; primary extensor of the vertebral column, : originate outside the eye and insert onto the outer surface of the white of the eye, and create eyeball movement, : front part of the occipitofrontalis muscle, : muscle that originates on the mandible and allows the tongue to move downward and forward, : muscle that depresses the mandible, and raises and pulls the hyoid bone anteriorly, : muscle that originates on the hyoid bone to move the tongue downward and flatten it, : muscle of the iliocostalis group associated with the cervical region, : laterally placed muscles of the erector spinae, : muscle of the iliocostalis group associated with the lumbar region, : muscle of the iliocostalis group associated with the thoracic region, : anterior neck muscles that are attached to, and inferior to the hyoid bone, : muscle that moves the mandible from side to side, : muscle of the longissimus group associated with the head region, : muscle of the longissimus group associated with the cervical region, : intermediately placed muscles of the erector spinae, : muscle of the longissimus group associated with the thoracic region, : main muscle for chewing that elevates the mandible to close the mouth, : longest scalene muscle, located between the anterior and posterior scalenes, : muscle of the lumbar region that helps extend and laterally flex the vertebral column, : muscle that lifts the hyoid bone and helps press the tongue to the top of the mouth, : posterior part of the occipitofrontalis muscle, s: muscle that makes up the scalp with a frontal belly and an occipital belly, : muscle that has superior and inferior bellies and depresses the hyoid bone, : muscle that originates on the soft palate to elevate the back of the tongue, : smallest scalene muscle, located posterior to the middle scalene, : flex, laterally flex, and rotate the head; contribute to deep inhalation, : interspinales and intertransversarii muscles that bring together the spinous and transverse processes of each consecutive vertebra, : transversospinales muscle associated with the head region, : transversospinales muscle associated with the cervical region, : transversospinales muscle associated with the thoracic region, : muscle of the spinalis group associated with the head region, : muscle of the spinalis group associated with the cervical region, : medially placed muscles of the erector spinae, : muscle of the spinalis group associated with the thoracic region, : posterior neck muscles; includes the splenius capitis and splenius cervicis, : neck muscle that inserts into the head region, : neck muscle that inserts into the cervical region, : major muscle that laterally flexes and rotates the head, : muscle that depresses the larynx’s thyroid cartilage, : muscle that originates on the styloid bone, and allows upward and backward motion of the tongue, : muscle that elevates the hyoid bone posteriorly, : neck muscles that are superior to the hyoid bone, : muscle that depresses the hyoid bone and elevates the larynx’s thyroid cartilage, : muscles that originate at the transverse processes and insert at the spinous processes of the vertebrae, pper Appendicular Muscles: Shoulders, arms, and Hands, : muscle that inserts into the first metacarpal, : small muscle on the lateral posterior elbow that extends the forearm, : (anterior flexor compartment of the arm) the biceps brachii, brachialis, brachioradialis, and their associated blood vessels and nerves, : (anterior flexor compartment of the forearm) deep and superficial muscles that originate on the humerus and insert into the hand, : two-headed muscle that crosses the shoulder and elbow joints to flex the forearm while assisting in supinating it and flexing the arm at the shoulder.
