Document Summary

Sternoclavicular joint is only articulation with the rest of the body. Tendon of biceps brachii muscle passes b/w greater tubercle and lesser tubercle in the intertubercular groove (or bicipital groove) Infraglenoid tubercle: course of axillary nerve through this area before it gets to surgical neck of humerus. Coracohumeral ligaments (b/w coracoid process to humerus) Glenohumeral ligaments (thickens part of the glenohumeral capsule) Coracoacromial ligament (coracoid process to acromium process both on same bone: over glenohumeral joint. Coracoclavicular ligaments maintain the complex b/w scapula and clavicle important for keeping scapula and clavicle together, if these are injured -: trapezoid ligament (trapezoid shaped, conoid ligament (cone shaped) Suprascapular ligament: closes the suprascapular notch. In some people this ligament can become osseous -> named suprascapular foramen: pathway for suprascapular neurovasculature. Large humeral head attached to small glenoid fossa (of scapula) Tendon of long head of biceps brachii muscle is inside the joint and attaches to the glenoid labrum.
