[hyo̅o̅′mərəs] pl. humeri

Etymology: L, shoulder

the bone of the upper arm, from the elbow to the shoulder joint where it articulates with the scapula. It comprises a body, a head, and two condyles. The body is almost cylindric proximally and prismatic and flattened distally and has two borders and three surfaces. The nearly hemispheric head articulates with the glenoid cavity of the scapula and has a constriction called the surgical neck, frequently the seat of a fracture. The condyles at the distal end have several features that articulate with the radius and ulna. Also called arm bone. humeral, adj.

humerus

the bone of the upper forelimb, extending from shoulder to elbow. It consists 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 distal end of the humerus has a trochlea, which articulates with the ulna, and a capitulum, which articulates with the radius, at the elbow. See also Table 10.
