A transverse spine of scapula divides the posterior surface of the scapula into a smaller supraspinous fossa above and a larger infraspinous fossa below. As it continues laterally, this spine forms the acromion (the bony high point of the shoulder). The subscapular fossa is on the anterior surface of the scapula. At the lateral angle of the

The scapula is a flat, triangular shaped bone, positioned on the posterior surface of the thoracic cage, spanning ribs 2-7.

It is comprised of the scapular body, neck, … Anterior, or costal surface of the scapula.The Latin term for that surface (facies subcostalis) may be misleading as "subcostal" mean "below rib" that corresponds to the scapula's location only in case the human is in the supine position. The scapula has a triangular body with three main processes coming off the body. On the posterior side is the spine of the scapula that ends in the acromion process, which articulates with the lateral end of the scapula.On the anterior side, facing into the body, is a right-angled process called the coracoid process.While at the superior lateral edge of the scapula the glenoid cavity, which 2017-12-07 2015-06-01 The scapula, or shoulder blade, is a large triangular-shaped bone that lies in the upper back.
