Attachments, innervation and functions of the rotator cuff muscles. Teres minor muscle Musculus teres minor 1/2 Synonyms: none In the human body, the rotator cuff is a functional anatomical unit located in the upper extremity. Its function is related to the glenohumeral joint, where the mus...
To recall the muscles of the anterior compartment of the arm, remember “BBC”: Biceps Brachialis Coracobrachialis Cross-section of the arm, featuring the anterior and posterior compartments. Note the brachial fascia enclosing all of the muscles and forming the lateral and medial intermuscular sep...

and the smoothness of physical actions. Perichondrium (connective tissue membrane surrounding cartilage) compensates for the absence of vasculature in cartilage by providing nutrition and support.Cartilage: Histology, and bursae. The muscles ensure the mobility and stability of the shoulder and upper li...
The tendon is a "mechanical bridge," transmitting muscle forces to the bones and joints. This tough, fibrous structure also helps muscles complete joint movements along a plane. The tendon type reflects its associated muscle's morphology and function. Tendon tissue is present throughout an entire...
图形1 - Axial T1 FS image shows the normal anatomy of the glenohumeral joint and the rotator cuff on a MR (Magnetic Resonance) arthrography of the shoulder. On this MRI the labrum, the tendons of the rotator cuff muscles, the glenohumeral ligaments, the articular capsule and the subacromial-...
Rotator cuff muscles (subscapularis, supraspinous, infraspinous and teres minor) embrace the shoulder joint. Subscapularis Subscapularis lies on the inner side of the scapula (between the scapula and the ribs). Origin: Front side (subscapular fossa) of the scapula ...
