===Ulna===

The Ulna's greatest contribution to functional anatomy is in the formation of the '''Olecranon''', or the point of the elbow, which gives rise to the attachment of the '''triceps'''. The olecranon articulates with the humerus via its anconeal process.  Distally (where unfused), the '''lateral styloid process''' articulates with the '''ulnar carpal bone'''.

*The ulna shaft tapers distally, lying oblique to the radius, i.e. the proximal end lies medial and the distal end lateral to the radius.

*There is a distinct gap between it and the radius, which is filled by the pronator quadratus muscle.

*The distal styloid process is blunt and articulates with the ulnar carpal bone, accessory carpal bone and ulnar notch of the radius.
