Study Notes
Medial and Lateral Epicondyles
- The medial epicondyle (epicondylus medialis) is a projection superior and medial to the medial condyle of the humerus.
- The ulnar nerve passes over the smooth posterior surface of the medial epicondyle.
- Muscles in the anterior compartment of the forearm originate on the anterior surface of the medial epicondyle.
- The lateral epicondyle (epicondylus lateralis) is an impression at the end of the humerus's lateral border.
- Seven muscles in the posterior compartment of the forearm originate on the lateral and anterior surfaces of the lateral epicondyle.
