The ulna doesn't ve any contact with any bone from the hand
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.
Both the radius and ulna move with the hand in a rotational sense.
The wrist bone would be the Ulna. carpals..
Styloid process of the ulna & radius.The temporal bone, the radius bone, and the ulna bone.
-Ulna bone: elbow bone -Radius bone: Forearm bone The radius is the bone of the forearm that extends from the lateral side of the elbow to the thumb side of the wrist. The radius is situated on the lateral side of the ulna, which exceeds it in length and size. It is a long bone, prism-shaped and slightly curved longitudinally.
The humerus, radius, and ulna are the bones of your arm. The humerus is the upper arm bone. In the forearm, the radius is the larger bone on the "thumb side," and the ulna is the smaller bone on the "pinkie" side.
The bone in the arm between the elbow and wrist is called the radius. It runs next to the ulna, which is the other bone in the forearm. These two bones play a crucial role in supporting the forearm and enabling movements of the wrist and hand.
if you are talking about the forearm bone next to the ulna, that would be the radius.
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.
You can tell the radius and the ulna apart by their size. The radius is bigger than the Ulna. The ulna also helps to form the elbow joint and the radius helps to move the hand upwards and downwards with the help of the ulna.
Your Radius is on the thumb side of ur body.
The ulna articulates with:the humerus at its proximal end (end closest to the elbow)the radius at its radial notch (near the top part of the ulna) and at the ulnar notch (near the bottom part of the ulna)the wrist (separated by a fibrocartilaginous disc) at its distal end (end closest to the hand)
