The olecranon process, the ulnar nerve.... What are they? With a model of the human elbow, you'll learn all about these! The human elbow is one of its most commonly engaged joints, and while its structure may seem simple, it includes a number of prominent bony landmarks. The ulnar nerve, more commonly known as the "funny bone," also makes its home there. It also can experience a number of injuries, such as tennis elbow and a number of muscular injuries. To help facilitate a full study, Anatomy Warehouse has collected a number of models for students and medical professionals alike.
