Humeral Head
The head (caput humeri), nearly hemispherical in form. It 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.

Famous quotes containing the word head:
“A lioness, with udders all drawn dry,
Lay couching, head on ground, with cat-like watch
When that the sleeping man should stir; for ‘tis
The royal disposition of that beast
To prey on nothing that doth seem as dead.”
—William Shakespeare (1564–1616)
