The Glenoid fossa is so called when is not surrounded by the Glenoid labrum (which increases its depth and also increases the surface of contact with the head of the humerus). In a specimen (or in a human body) the glenoid labrum is present, therefore the Glenoid fossa is called Glenoid cavity (deeper). Basically the difference is in the presence of the glenoid labrum... not really the same thing.

The glenoid fossa is a concavity on the temporal bone of the skull, while the glenoid cavity is a shallow socket on the scapula bone of the shoulder joint. The glenoid fossa is part of the skull's temporomandibular joint, where the mandible articulates. The glenoid cavity is part of the shoulder joint, where the humerus articulates.
The cavity that serves as the socket of the scapula is called the glenoid cavity or glenoid fossa. This cavity articulates with the head of the humerus to form the shoulder joint.

The femur bone is a strong bone in the human thigh.
The humerusOn the lateral angle of the scapula is a shallow pyriform, articular surface, the glenoid cavity (or glenoid fossa) of scapulaComes from Greek: gléne, "socket"), which is directed lateralward and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest.
The glenoid labrum
There is typically one glenoid fossa in the human body, located on the scapula bone.
scapula
The depression in the scapula can be either one of four different structures; the supraspinatus fossa, the infraspinatus fossa, the subscapular fossa, or the glenoid fossa. The problem is that none of these articulate with the ulna. The bone you are probably looking for is the humerus, and it articulates with the last one I mentioned, the glenoid fossa.
On the scapula, near the glenoid fossa
The scapula is divided by acromion, coracoid and Glenoid fossa.
The humerus articulates with the scapula at the glenoid fossa to form the shoulder joint. Specifically, the head of the humerus sits in the shallow, concave glenoid cavity of the scapula. This ball-and-socket joint allows for a wide range of motion in the shoulder.
