Lateral epicondyle of the humerus
Encyclopedia
The lateral epicondyle of the humerus
is a small, tuberculated eminence, curved a little forward, and giving attachment to the radial collateral ligament
of the elbow-joint, and to a tendon
common to the origin of the Supinator and some of the Extensor muscles. In birds, where the arm is somewhat rotated compared to other tetrapod
s, it is termed dorsal epicondyle of the humerus.

Radial collateral ligament (elbow)
The radial collateral ligament is a short and narrow fibrous band, less distinct than the ulnar collateral, attached, above, to a depression below the lateral epicondyle of the humerus; below, to the annular ligament, some of its most posterior fibers passing over that ligament, to be inserted...

Tendon
A tendon is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension. Tendons are similar to ligaments and fasciae as they are all made of collagen except that ligaments join one bone to another bone, and fasciae connect muscles to other...

Tetrapod
Tetrapods are vertebrate animals having four limbs. Amphibians, reptiles, birds and mammals are all tetrapods; even snakes and other limbless reptiles and amphibians are tetrapods by descent. The earliest tetrapods evolved from the lobe-finned fishes in the Devonian...
