| temporal | muscle located above and near the ear |
| masseter | used when biting and chewing, moves lower jaw |
| trapezius | triangular-shaped muscle that extends across the back of the shoulder, covers the back of the neck; pulls shoulder blades together |
| latissimus dorsi | lower back, extends to axilla (armpit) |
| pectoralis major | fan-shaped muscle that crosses the upper part of the front of the chest |
| deltoid | muscle covers the shoulder joint; one of the muscles used for intramuscular injections |
| gluteus maximus | forms most of the fleshy part of the buttock; it is a large muscle that offers support when an individual is standing |
| gluteus medius | smaller muscle located above the upper outer quadrant of the gluteus maximus muscle; one of the muscles used for intramuscular injections |
| hamstring muscles | located in the posterior part of the thigh; responsible for flexing the leg on the thigh |
| gastrocnemius | main muscle of the calf (meaning - calf bladder) |
| tibialis anterior | muscle is positioned on the front of the leg (shin splints) |
| arthralgia | pain in the joints |
| atrophy | wasting away |
| contracture | an abnormal (usually permanent) bending of a joint into a fixed position; usually caused by atrophy and shortening of muscle fibers |
| insertion | point of attachment more mobile |
| involuntary muscle | muscles that act without conscious control |
| origin | point of attachment of a muscle to a bone that is less movable |
| pelvic girdle weakness | weakness of the muscles of the pelvic girdle; muscular dystrophy |
| skeletal muscle | muscles that attach to the bones of the skeleton; skeletal muscles act voluntarily; aka striated muscle |
| smooth muscle | muscles found in the walls of hollow organs and tubes; aka visceral muscles; act involuntarily |
| striated muscle | muscles that have a striped appearance; skeletal and cardiac muscles are examples |
| tendon | attaches muscle to bone |
| torso | aka trunk or midsection |
| visceral muscle | muscles of the internal organs; aka smooth muscle |
| voluntary muscle | muscles that operate under conscious control; skeletal muscles are examples |
| muscular dystrophy | group of genetically transmitted disorders characterized by progressive symmetrical wasting of skeletal muscles; no evidence of nerve involvement or degeneration of nerve tissue |
| rotator cuff tear | tear in the muscles that form a "cuff" over the upper end of the arm; most common of shoulder injuries |
| strain | injury to the body of the muscle or attachment of the tendon, resulting from overstretching, overextension, or misuse; muscle pull |
| muscle biopsy | extraction of a specimen of muscle tissue, for the purpose of examining it under a microscope |
| electromyography | process of recording the strength of the contraction of a muscle when it is stimulated by an electric current |
| flexion | bending motion, which decreases the the angel between two bones |
| extension | straightening motion, which increases the angle between two bones |
| abduction | movement of bone away from the midline |
| adduction | movement of a bone toward the midline |
| rotation | turning of a bone on its own axis |
| supination | turning palm upwards |
| pronation | turning palm downward |
| dorsiflexion | narrows the angle between top of foot and leg (flex) |
| plantar flexion | increases the angle (ballerina) |
| circumduction | circular motion |
