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
The condyloid process or condylar process is the process on the human and other mammalian species' mandibles that ends in a condyle, the mandibular condyle.It is thicker than the coronoid process of the mandible and consists of two portions: the condyle and the constricted portion which supports it, the neck.
The temporomandibular joints are the dual articulation of the mandible with the skull. Each TMJ is classed as a "ginglymoarthrodial" joint since it is both a ginglymus (hinging joint) and an arthrodial (sliding) joint, [42] and involves the condylar process of the mandible below, and the articular fossa (or glenoid fossa) of the temporal bone ...
The condyle can only be in the same place as it was the last time it was positioned by the dentist if it is consistently moved to the most superior and anterior position within the fossa. It is a physiologic position that is used for reproducibility. The Temporomandibular Joint is not restricted to Centric Relation in function.
The glenoid cartilage underneath the labrum in the glenohumeral (GH) joint is disrupted by glenolabral articular disruption. [5] The articulation of the humeral head inside the glenoid fossa of the scapula forms the GH joint itself, which is a synovial ball and socket joint.

In anatomy, a fossa (/ ˈ f ɒ s ə /; [1] [2] pl.: fossae (/ ˈ f ɒ s iː / or / ˈ f ɒ s aɪ /); from Latin 'ditch, trench') is a depression or hollow, usually in a bone, such as the hypophyseal fossa (the depression in the sphenoid bone). [3]
