<Tr> <Td_colspan="2"> Anatomical terms of bone (edit on Wikidata) </Td> </Tr> <P> The upper or proximal extremity of the humerus consists of the bone's large rounded head joined to the body by a constricted portion called the neck, and two eminences, the greater and lesser tubercles . </P> <P> The head (caput humeri), is nearly hemispherical in form . It is directed upward, medialward, and a little backward, and articulates with the glenoid cavity of the scapula to form the glenohumeral joint (shoulder joint). 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 . The diameter of the humeral head is generally larger in men than in women . </P> <P> The anatomical neck (collum anatomicum) is obliquely directed, forming an obtuse angle with the body . It is best marked in the lower half of its circumference; in the upper half it is represented by a narrow groove separating the head from the tubercles . It affords attachment to the articular capsule of the shoulder - joint, and is perforated by numerous vascular foramina . Fracture of the anatomical neck rarely occurs . </P>
