BIOB33H3 Study Guide - Final Guide: 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.
