BIOB33H3 Lecture Notes - Lecture 6: Shoulder Girdle, Biceps, Serratus Anterior Muscle
Document Summary
Appendicular musculature: muscles of the pectoral girdle and upper limbs, muscles that position the pectoral girdle. These muscles also coordinate with the muscles that move the arm. Vertebral border of margins of ribs 1-9 scapula. Depresses and protracts superior margins of ribs scapula. Occipital bone and spinous processes of thoracic vertebrae: muscles that move the arm, anterior view. Long head- supraglenoid tubercle of scapula shoulder , downward rotation of scapula and elevates neck. May elevate, retract, depress or rotate scapula depending on other muscles and extend neck. Flexes the lower arm: posterior view, rotator cuff- muscles that stabilize the glenohumeral (shoulder) joint. Humerus scapula: other muscles that move the arm (posterior view) Adduction and medial rotation at the shoulder: muscles that move the forearm and hand, flexion.
