The bones of the shoulder girdle are the clavicle
(KLAV-ih-kl) and the scapula (SKAP-you-lah). The
clavi-cle or collarbone is a long slim bone located at the
root of the neck just below the skin and anterior to the first
rib. The medial end articulates with the manubrium of the
sternum and the lateral end with the acromial (ah-KRO-
mee-al) process of the scapula. The scapula or shoulder
blade is a large, flat, triangular bone located on the dorsal
portion of the thorax, covering the area from the second to
the seventh rib (Figure 7-18). Two other prominent bony
projections on the scapula are the coracoid process,
which functions as an attachment for muscles that move the
arm, and the glenoid fossa, which receives the head of
the humerus and helps form the shoulder joint.
