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.

The Humerus is the long bone of the forearm, articulating with the scapula to form the shoulder and the radius and ulna to form the elbow. In situ, it lies obliquely along the ventral thorax and is more horizontal in larger species. The greater tubercle is not separated into two parts like in other species. In dogs and cats, it articulates with the ulna medially via a '''trochlea''' and the radius laterally via a '''capitulum'''.
