===[[Forelimb - Anatomy & Physiology#Humerus|Humerus]]===

The humerus represents the first part of the limb that is a free appendage, i.e. it does not have any firm attachment to the trunk. The humerus is a long bone that has a large articular head which articulates with the glenoid cavity of the scapula (see above). This articular head is slightly offset via a neck to facilitate articulation. The head itself has two processes, the ''greater tubercle'' which is found laterally and the ''lesser tubercule'' that is found medially.

This articular head is slightly offset via a neck to facilitate articulation. The head itself has two processes, the ''greater tubercle'' which is found laterally and the ''lesser tubercule'' that is found medially. These tubercules are seperated by an intertubercular groove across which the biceps tendons run. The lateral tubercule forms the anatomical landmark of the point of the shoulder and in canines this can be readily palpated.
