===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''' muscle.  The olecranon articulates with the humerus via its anconeal process.  Distally (where unfused), the '''lateral styloid process''' articulates with the '''ulnar carpal bone'''.

The olecranon develops as an apophysis, i.e.. from a separate site of ossification.  Distally (where unfused), the '''lateral styloid process''' articulates with the '''ulnar carpal bone'''.
