Identify the structure in the diagram below
The Correct Answer is ["Ulna bone"]
The ulna is one of the two bones of the forearm, located on the medial (inner) side of the arm.
It is a long bone that runs parallel to the radius bone, extending from the elbow joint to the wrist joint.
The ulna features several surface landmarks, including the olecranon process, which forms the bony tip of the elbow.
The bone is also involved in the formation of the elbow joint, where it articulates with the humerus bone, and the wrist joint, where it articulates with the radius bone and several carpal bones.
The ulna is an important site for the attachment of muscles involved in forearm and wrist movements.
