The glenoid fossa of the scapula or the glenoid cavity is a bone part of the shoulder.The word glenoid is pronounced / ˈ ɡ l iː n ɔɪ d / or / ˈ ɡ l ɛ n ɔɪ d / (both are common) and is from Greek: gléne, "socket", reflecting the shoulder joint's ball-and-socket form. [1]
The mandibular fossa, also known as the glenoid fossa in some dental literature, is the depression in the temporal bone that articulates with the mandible. Structure [ edit ]
The glenoid labrum (glenoid ligament) is a fibrocartilaginous (but not fibrocartilage, as previously thought) structure attached around the rim of the glenoid cavity on the shoulder blade. The shoulder joint is considered a ball-and-socket joint .
The rotator cuff muscles of the shoulder produce a high tensile force, and help to pull the head of the humerus into the glenoid cavity. The glenoid cavity is shallow and contains the glenoid labrum which deepens it and aids stability. With 120 degrees of unassisted flexion, the shoulder joint is the most mobile joint in the body.

In anatomy, the temporomandibular joints (TMJ) are the two joints connecting the jawbone to the skull. It is a bilateral synovial articulation between the temporal bone of the skull above and the condylar process of mandible below; it is from these bones that its name is derived. The joints are unique in their bilateral function, being ...
The supraglenoid tubercle is a region of the scapula from which the long head of the biceps brachii muscle originates. [1] [2] It is a small, rough projection superior to the glenoid cavity near the base of the coracoid process.
In other words, without the rotator cuff, the humeral head would ride up partially out of the glenoid fossa, lessening the efficiency of the deltoid muscle. The anterior and posterior directions of the glenoid fossa are more susceptible to shear force perturbations, as the glenoid fossa is not as deep relative to the superior and inferior ...
