The elbow is the region between the upper arm and the forearm that surrounds the elbow joint. [1] The elbow includes prominent landmarks such as the olecranon , the cubital fossa (also called the chelidon, or the elbow pit), and the lateral and the medial epicondyles of the humerus .
Therefore, the body has its feet together (or slightly separated), and its arms are rotated outward so that the palms are forward, and the thumbs are pointed away from the body (forearms supine). As well, the arms are usually moved slightly out from the body, so that the hands do not touch the sides.
External rotation (lateral rotation or extorsion) is rotation away from the center of the body, [22] carried out by external rotators. Internal and external rotators make up the rotator cuff , a group of muscles that help to stabilize the shoulder joint .
These two terms, used in anatomy and embryology, describe something at the back (dorsal) or front/belly (ventral) of an organism. [2] The dorsal (from Latin dorsum 'back') surface of an organism refers to the back, or upper side, of an organism. If talking about the skull, the dorsal side is the top.
The radius can thus glide on the capitulum during elbow flexion-extension while simultaneously rotate about its own main axis during supination-pronation. [2] Between the capitulum and the trochlea of the humerus is the capitulotrochlear groove. A semi-lunar surface around the circumference of head is shaped to articulate continuously with this ...

Most of the large number of muscles in the forearm are divided into the wrist, hand, and finger extensors on the dorsal side (back of hand) and the ditto flexors in the superficial layers on the ventral side (side of palm). These muscles are attached to either the lateral or medial epicondyle of the humerus. They thus act on the elbow, but ...
