In the glenohumeral joint (shoulder), there are two bursae, located in a sliding zone between a virtual space formed by the acromioclavicular arch, which is formed by the relationship between the acromion bone and the coracoid process of the clavicle. This relationship is given by the coracoacromial ligament in a way that a protective roof does not allow impact on the osteoligamentary structures (METZKER, 2010).
Regarding the shoulder, choose the CORRECT alternative:


A The shoulder is a biaxial joint with two degrees of freedom and performs three movements.
B The shoulder performs the movements of flexion, extension, abduction, adduction, medial rotation, inversion, and circumduction.
C The scapulohumeral rhythm allows 0 to 90° of flexion amplitude with elevation. The long head of the biceps stabilizes the humeral head, resisting pressure force.
D The rotator cuff is a dynamic stabilizer that prevents the slipping of the humeral head out of the glenoid cavity of the scapula during daily activities.
