BONES OF THE PECTORAL GIRDLE
The two pectoral girdles, right and left, provide attachment sites for muscles of the shoulder and
brachium. Each pectoral girdle consists of a scapula, or shoulder blade, and a clavicle, or collar-
bone.
Clavicle: A slender, double-curved bone that attaches the upper limbs to the axial skeleton. It
includes the following features:
●
Sternal end: the blunt, medial extremity, which articulates with the manubrium of the
sternum.
Acromial end: the slightly flattened lateral extremity, which articulates with the acro-
mion of the scapula.
Scapula: A triangular bone with projections for muscle attachment. It contains many features,
which include:
Spine: the narrow ridge on the posterior side.
Acromion: a flattened, prominent process at the lateral end of the spine.
=
Coracoid process: a beak-like process superior and medial to the glenoid cavity (corac =
crow + -oid = resemblance to).
Glenoid cavity: a socketed depression inferior to the acromion, which…
