Detailed explanation-1: -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 radius and the ulna are long, slightly curved bones that lie parallel from the elbow, where they articulate with the humerus, to the wrist, where they articulate with the carpals. The radius is located laterally, near the thumb, and the ulna medially, near the little finger.

Detailed explanation-3: -The forearm is the region of the upper limb that extends from the elbow to the wrist. ulna bone (os ulna) supports the medial (little finger) side.

Detailed explanation-4: -Like the radius, the ulna has a styloid process consistent with its location on the antebrachium. The ulnar styloid process, when it is in anatomical position, will always face medially. Alternately, the radial notch of the ulna will always be on the lateral side. The trochlear notch will be on the anterior side.

Detailed explanation-5: -Ulna. The ulna is one of the two forearm bones and is on the small finger side of the forearm. Unlike the radius, this bone does not twist, so when the hand changes position, the ulna is always in the same position on the inside part of the forearm.
