The lateral angle of the scapula or glenoid angle, also known as the head of the scapula, is the thickest part of the scapula. It is broad and bears the glenoid fossa on its articular surface which is directed forward, laterally and slightly upwards, and articulates with the head of the humerus .
The lateral border, or base, the shortest of the three, is slightly concave; its edge, thick and round, is continuous above with the under surface of the acromion, below with the neck of the scapula. It forms the medial boundary of the great scapular notch, which serves to connect the supra- and infraspinatous fossae.
It fixes the scapula into the thoracic wall and aids in rotation and abduction of the shoulders. [citation needed] subclavius: Located beneath the clavicle, originating from the first rib and inserting on the subclavian groove of the clavicle. [3] It depresses the lateral clavicle [3] and also acts to stabilize the clavicle. [citation needed ...
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]
When the scapula is moved laterally it lies in a sagittal plane with the glenoid cavity facing anteriorly. At this position, the lateral end of the clavicle is rotated anteriorly so that the clavicle lies in a frontal plane. While this slightly closes the angle between the clavicle and the scapula, it also widens the shoulder. [4]: 40
The coracoid process (from Greek κόραξ, raven [1]) is a small hook-like structure on the lateral edge of the superior anterior portion of the scapula (hence: coracoid, or "like a raven's beak"). Pointing laterally forward, it, together with the acromion, serves to stabilize the shoulder joint.
The glenoid tubercles are two small bony eminences (or tubercles) located above and below the glenoid cavity on the scapula. The glenoid tubercles consist of the supra-and the infraglenoid tubercle. The Latin terms supra and infra meaning above and below respectively refers to the tubercles location in relation to the glenoid cavity.
In human anatomy, the acromion (from Greek: akros, "highest", ōmos, "shoulder", pl.: acromia) is a bony process on the scapula (shoulder blade). Together with the coracoid process, it extends laterally over the shoulder joint. The acromion is a continuation of the scapular spine, and hooks over anteriorly.
