肱骨头 - Caput humeri

影像

描述

The head of humerus, nearly hemispherical in form, is directed upward, medialward, and a little backward, and articulates with the glenoid cavity of the scapula.

The circumference of its articular surface is slightly constricted and is termed the anatomical neck, in contradistinction to a constriction below the tubercles called the surgical neck which is frequently the seat of fracture. Fracture of the anatomical neck rarely occurs.
