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 glenoid fossa (shoulder socket) is positioned on the posterolateral (outer and rear) edge of the scapulocoracoid, a position significantly more lateral than other Devonian tetrapods (apart from Tulerpeton). Above the glenoid fossa is a raised area known as the supraglenoid buttress.
The coracoid is small and rounded, and forms a down and rearward facing glenoid fossa with the scapula. The ilium of the pelvic (hip) girdle has a prominent posterior process and supraacetabular crest—a ridge of bone over the acetabulum. The acetabulum itself is relatively large and almost completely closed, unlike the fully open acetabulum ...
The narrowest point of the scapular blade is towards the head of the glenoid fossa. The ventral edge of the scapula lacks a distinct enthesis, which may also represent an ontogenetic trait. The glenoid fossa has an oval outline and is large. The humerus is short, with a large deltopectoral crest. The proximal end of the femur has a width that ...
Odobenocetops (/ ˌ oʊ d ə b iː ˈ n ɒ s ɪ t ɒ p s /) is an extinct genus of small toothed whale known from Chile and Peru.Its fossils are found in Miocene-aged marine strata of the Bahía Inglesa Formation and Pisco Formation.
Both this feature and the size of the glenoid fossa are more similar to polar bears than lions or tigers. The humerus is also similar to that of Ursus , as well as Amphicyon , but it lacked the deep olecranon fossa , and the associated secure locking of the ulna in the fossa, which prevents lateral bending of the elbow joint, making the ...
The scapular blade of Wadiasaurus is long, narrow, and slender, and with the coracoid plate it form an outward, open-notched glenoid fossa that faces caudolaterally with sharply defined upper and lower lips. [9] The scapular side of the glenoid fossa is slightly concave whereas the
The acromion process of the scapula is positioned directly above the glenoid fossa and projects exactly upright to the side surfaces of the scapular blade. The scapular blade has a distinct surface on the ventral surface that would have supported the muscle M. triceps longus caudalis.
