Humerus

Humerus is the longest bone in the upper limb. It has three parts- head, shaft and inferior portion called the condylar part. The head is connected to the shaft via two necks- anatomical and surgical neck. The anatomical neck connects the articular head with the two (greater and lesser tuberosities, while the surgical neck is the weakest portion that joins the shaft with the head. It is most liable to fracture.

The humerus has three borders (lateral, medial and anterior).

Humerus has three surfaces- anterolateral surface (between anterior and lateral borders), anteromedial surface (between anterior and medial borders) and posterior surface (between medial and lateral surfaces).
