Module 9 Pectoral girdle - Comprised of two bones, a scapula and a clavicle they meet at the acromioclavicular joint - The pectoral girdle is made u of the clavicle anterior side and attaches to the scapula from the acromioclavicular joint posteriorly. - Movements of the pectoral girdle - Protraction and retraction - Elevation and depression - Upward rotation and downward rotation - The pectoral girdle is designed so that the clavicle and scapular move as a unit - Pectoralis major - Two heads clavicular head and sternocostal head - Pectoralis major 3^rd^ -- 5^th^ head - Subclavius junction of 1^st^ rib and costal cartilage - Serratus anterior -- external surfaces of lateral parts of 1^st^ and 8^th^ rib Posterior muscles The trapezius -- the most superficial muscle of the back, inserts in the scapula Brachial plexus - Combines into three trunks -- superior, middle, inferior -  Trapezius -- most visible, has three different movements ( descending fibres )  clavicle anatomy - Apex -- 7^th^ rib Sternum - Sterno-clavicular joint -- only articulation with the axial skeleton - Saddle joint, some rotation Acromioclavicular joint - Lateral end of clavicle and acromion of scapula Module 10  Glenohumeral - Flexion and extension, abduction and adduction - Consists of glenoid and humerus  A diagram of a joint Description automatically generated Movements of the glenohumeral joint - Flexion and extension - Abduction and adduction - Medial and lateral rotation - Hyperextension - Circumduction Muscles acting on the glenohumeral joint - Scapulohumeral muscles - Sits - Teres major - Deltoid - Axioappendicular muscles - Pectoralis major - Latissimus dorsi
