Multiple Choice

The humeral-radial joint of the horse is commonly known as?

Elbow joint. The articulation between the humerus (upper arm bone) and the radius (forearm bone) in the horse forms the elbow, a hinge joint that mainly flexes and extends. The shoulder is the joint where the scapula meets the humerus, not between the humerus and radius, so that’s separate. The terms knee and wrist refer to the carpal region in horses (the knee being carpal anatomy in a way that can be confusing to lay terms), not the connection between the upper arm and forearm. So the humeral-radial joint is the elbow.
