The scapula (pl.: scapulae or scapulas [1]), also known as the shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other.
While this slightly closes the angle between the clavicle and the scapula, it also widens the shoulder. [4]: 40 The scapula can be elevated and depressed from the neutral position to a total range of 10 to 12 centimetres (3.9 to 4.7 in); at its most elevated position the scapula is always tilted so that the glenoid cavity is facing superiorly.
The coracoid process acts as an attachment and origin for a large number of muscles (attached muscles not labeled here). The coracoid process is a thick curved process attached by a broad base to the upper part of the neck of the scapula; [2] it runs at first upward and medially; then, becoming smaller, it changes its direction, and projects forward and laterally.

Different types of bone markings and features. A condyle is the round prominence at the end of a bone, most often part of a joint – an articulation with another bone. [2] The epicondyle refers to a projection near a condyle, particularly the medial epicondyle of the humerus. [3] These terms derive from Greek. [4] [a]
Blood tests are also often used to identify associated antibodies. "About 80% of patients with MG are positive" for the antibody behind the immune system dysfunction, says Weidmayer.
The movement of the scapula across the rib cage in relation to the humerus is known as the scapulohumeral rhythm, and this helps to achieve a further range of movement. This range can be compromised by anything that changes the position of the scapula. This could be an imbalance in parts of the large trapezius muscles that hold the scapula in ...
Our Town marks a Broadway return for Holmes, who made her debut in the 2008 revival of All My Sons, and later starred in the 2012 play Dead Accounts. Holmes noted that Our Town is a particularly ...
