GROSS ANATOMY

Detailed explanation-1: -Where is the ulna located? The ulna is one of two bones in your forearm. The other is your radius. The ulna is on the medial (pinkie) side of your forearm.

Detailed explanation-2: -The ulna is the medial bone of the forearm and the longer of the two parallel forearm bones. Like the radius, the ulna also has three main parts: a proximal end, shaft and a distal end. The proximal end articulates with the distal humerus and the head of the radius.

Detailed explanation-3: -The radius is on the lateral side of the arm, while the ulna is medial. The radius can turn at the elbow joint, and therefore the part of the radius that articulates with the humerus, called the radial head, has a rounded circumference that allows it to rotate in contact with the proximal ulna.

Detailed explanation-4: -The ulna (pl. ulnae or ulnas) is a long bone found in the forearm that stretches from the elbow to the smallest finger, and when in anatomical position, is found on the medial side of the forearm. That is, the ulna is on the same side of the forearm as the little finger.

Detailed explanation-5: -The ulna forms the skeleton of the medial part of the forearm and is a long bone, consisting of an expanded proximal end, a shaft and a head at the distal end.
