humerus

humerus

 [hu´mer-us] (pl. hu´meri) (L.)

the bone of the upper arm, extending from shoulder to elbow, consisting of a shaft and two enlarged extremities. The proximal end has a smooth round head that articulates with the scapula to form the shoulder joint. Just below the head are two rounded processes called the greater and lesser tubercles; the area just below the tubercles is called the “surgical neck,” because of its liability to fracture. The distal end of the humerus has two articulating surfaces: the trochlea, which articulates with the ulna, and the capitulum, which articulates with the radius at the elbow. and see Appendices.
