BIOB33H3 Lecture Notes - Lecture 7: Pronator Teres Muscle, Triceps Brachii Muscle, Shoulder Girdle
Document Summary
Abduction movement away from longitudinal axis. Plantar flexion standing on tip toe. Protraction move a body part anteriorly in a horizontal plane. Opposition special movement of thumb that causes pad to pad. Lateral flexion vertebral column moves side to side contact with any finger. Depression structure moves in a inferior motion. Elevation structure moves in a superior motion. Absorbs shocks and aids in strengthening joint areas. Two major groups of appendicular muscles: muscles of pectoral girdle and upper limbs, muscles of pelvic girdle and lower limbs. Muscles of the pectoral girdle and upper limbs. Teres minor adduction and lateral rotation of shoulder. Subscapularis medial rotation at the shoulder: triceps brachii extension of lower arm, latissimus dorsi adduction and medial rotation of, teres major extension and medial rotation at shoulder shoulder. Muscles that move the forearm and hand. ## adduct towards abduct away: flexion. Biceps brachii flexes at elbow and shoulder. Brachioradialis flexes at elbow: extension.
