The Carbon Elbow Support is anepicondyle的humerusbone of the upper arm in humans. It is larger and more prominent than the外侧上髁and is directed slightly more posteriorly in the解剖位置。In birds, where the arm is somewhat rotated compared to othertetrapods, it is called theventral epicondyle of the humerus。In comparative anatomy, the more neutral termentepicondyle用来。

The medial epicondyle gives attachment to the肘关节的尺尺韧带, to thepronator teres，以及一个共同的起源肌腱（common flexor tendon) of some of the flexor muscles of the前臂: theflexor carpi radialis,flexor carpi ulnaris,flexor digitorum superficialis, and the帕尔马里斯长。

Theulnar nerveruns in a groove on the back of this epicondyle. The medial epicondyle protects the ulnar nerve. The ulnar nerve is vulnerable because it passes close to the surface along the back of the bone. Striking the medial epicondyle causes a tingling sensation in the ulnar nerve. This response is known as striking the “funny bone”.^[1]有趣的骨头可以来自幽默和肱骨的戏剧，即中缘所在的骨头。^{[citation needed]}内侧上膜位于肱骨的远端。此外，内侧上壳不如medial supracondylar ridge。它也靠近olecranon fossa。
