Elbow, tendon of the biceps muscle
(Figs 3.52, 3.53)
The anterior aspect of the elbow is marked by the cubital crease,
extending from the lateral to the medial epicondyle of the humerus.
It is divided by the tendon of the biceps muscle. L.I.-11and
LU-5are located lateral to the tendon while P-3 and
HE-3are located medial to it.Lateral and medial epicondyles of the
humerus (Figs 3.53, 3.55, 3.56)
The lateral and medial epicondyles of the humerus form the lat-
eral aspects of the elbow. The olecranon is located between
them, on the posterior aspect of the elbow. The medial epi-
condyle is the origin of the extensor muscles of the wrist joint,
while the flexor muscles originate at the medial epicondyle.Tendon of
