Medial epicondyle of the humerus

Other Terms: Funny bone, Epicondylus medialis (Humerus), Epicondylus medialis humeri


This is the medial nonarticular process of the knuckle-like distal end of the humerus. It forms a prominent projection from the distal border of the medial supracondylar ridge. Its posterior surface forms a shallow groove for the ulnar nerve (this is the nerve, that when bumped, is referred to as "hitting the funny bone"), while its anterior aspect serves as the muscle attachment site for the superficial flexor muscles of the anterior antebrachium. It is subcutaneous in position and easily palpable.


The term epicondyle literally means upon the knuckle, from the Greek epi for upon and kondulos meaning knuckle or knob.
