Medial to the long head of the triceps brachii muscle
Inferior to the teres major muscle
Superior to the infraspinatus muscle
Superior to the subscapularis muscle
Inferior to the teres minor muscle Originate from anterior, superior and posterior aspects of the shoulder joint capsule Receive blood solely from branches of the axillary artery Contribute to the anterior and posterior walls of the axilla Have tendons which fuse with the capsule of the glenohumeral joint Are supplied by nerves branching from the inferior trunk of the brachial plexus Is separated from the teres major muscle by the tendon of the latissimus dorsi muscle Is innervated by the middle subscapular (thoracodorsal) nerve Receives blood from the circumflex scapular artery Inserts into the crest of the lesser tubercle Medially rotates and abducts the arm They play an important role in maintaining stability of the glenohumeral joint The inferior ligament underlies the tendon of the infraspinatus muscle Sensation or afferent information from them is transmitted along nerve fibers contained in ventral primary rami and dorsal roots They attach to the greater and lesser tubercles of the humerus None of the above It is rarely dislocated It is a synovial joint It has a tendon coursing within its capsule It is supported by the rotator cuff muscles It is one of the most mobile joints in the body Inferiorly Anteriorly Superiorly Posteriorly The scapular notch lies lateral to the coracoid process. The coracoid process lies superior to the clavicle. The acromion lies superior to the glenoid fossa. The supraglenoid tubercle arises from the inferior angle. The spine lies anterior to the acromion. Originates from the deltoid tubersity Is innervated by a nerve derived from anterior divisions of the brachial plexus. Initiates abduction of the arm. Is separated from the pectoralis major by the clavipectoral fascia Because of its circumpennate architecture, is a very powerful muscle Subscapularis Teres major Latissimus dorsi Supraspinatus Teres minor
