The capsule {capsula articularis) is attached, proximally, to thecircumference of the glenoid fossa and the labrum glenoidale; distallyit is attached to the anatomical neck of the humerus. It is strongestsuperiorly. It is strengthened by fusion with the tendons of themm. subscapularis, supraspinatus and infraspinatus, near theirinsertions. The transverse humeral ligament is a portion of the capsular liga-ment that bridges the groove between the tubercles of the humerus.

(Sobotla and McMurrich.) The coracohumeral ligament {lig. coracohumerale) is an accessoryligament that extends the base of the coracoid process and the baseof the greater tubercle of the humerus. It is partially fused withthe capsular ligament. The glenohumeral ligament consists of three bands of fibers thatstrengthen the ventral part of the capsule and are seen only upon itsinner aspect. They extend from the ventral margin of the glenoidfossa to the ventral part of the neck of the humerus. The head of the humerus is held against the glenoid fossa by mus-cular action and atmospheric pressure as the ligaments themselvesare too lax to do this. The synovial membrane lines the capsule and extends over thenonarticular portions of the bones within the capsular
