Correct. It is also proximally medial to the radius in pronation, however at its distal end it is lateral.
The right ulna is medial to the right radius. The right ulna is contralateral to the left radius.
radius (lateral) Ulna (medial)
In anatomical position the palms are facing up, making the ulna the medial bone of the forearm. The ulna is on the pinky side, and radius is on the thumb side.
The anatomical position of the radius bone (forearm bone) in relation to the ulna bone is due to the positioning of the thumb in the human hand. The radius is located lateral (on the same side as the thumb) to the ulna bone when the palms are facing up. This positioning allows for rotation of the forearm and greater range of motion in activities like grasping and rotating objects.
The antebrachium is the forearm. It contains the radius on the lateral side and the ulna on the medial side.
The 'Ulna'. It's your 'funny bone' bone, more or less.
The medial bump of the wrist is called the pisiform bone. It is a small, pea-shaped bone located on the palmar side of the wrist. It serves as an attachment site for some ligaments and muscles of the hand.
The medial and lateral epicondyles are located on the distal apsect of the humerus. The distal humerus articulates with the radius and ulna.
No. The radius is distal to the humerus. The humerus is proximal to the radius. :D
The bumps at the ankle are the malleoli (singular malleolus). The medial malleolus is formed by the tibia, and the lateral malleolus by the fibula. The medial wrist bump is formed by the styloid process of the ulna, and the lateral wrist bump by the styloid process of the radius.
The ulna and the radius are the two bones in the forearm. Latin: Ulnaris et. radialis. If you hold your arm at your side with the palm forward ulna is palpable on the medial (inside) part of the forearm, whilst the radius is palpable on lateral (outside) side. In layman terms, the radius is on the side of your thumb, and the ulna on the side of the pinky-finger.
The ulna is going to lateral to the radius (in anatomy terms). Otherwise the ulna is on the side where your pinky finger is.
