It is the radius or radial bone.
the radius. simple way to remember, when hitch hiking, your thumb is out, cars have radial tyres, your radius is up. or, just remember radius and ulna, the Ulna is Under.
a radius
There are actually two bones in your forearm, the ulna and the radius.
There are 2 bones in your forearm. The ulna and radius. They are connected at the parietal end to the humerus forming your elbow and at the distal end to the carpals forming your wrist.
the ulna is one of two bones in your forearm
It's one of two forearm bones.
It is one of two major bones in the forearm (the other one being the radius).
The two bones in the forearm allow it to turn better, so it is not necessary to turn the whole arm in oreder to slightly change the angle of the hand. There are three bones in the human arm (radius, ulna, humerus), so the question needs to be revised. If the question was supposed to be why having two bones in the FOREARM is better than one, then the answer is because having two bones is what allows the forearm to rotate. If there were only one bone in the forearm, then we would not be able to do so.
A pivot joint is found at the elbow. The forearm is between the elbow and the wrist and so has two main joints. One at the elbow and one at the wrist. The other at the wrist is a gliding joint.
There are two bones in your arm, but if it's the longer one in your forearm then it's called the ulna.
There are 3 bones in the arm. The forearm has 2 bones, the radius and ulna. The upper arm has one bone, the humerus.
Two bones in the forearm are not necessary. However, to function normally, both the ulna and radius bones are required. Without the radius bone, the forearm could not be rotated, and without the ulna, the forearm would have little strength.
There are three types of bones within the arm. The large bone is the humerus and is in the upper part of the arm. The radius is part of the forearm and are smaller bones. The ulna is another part of a bone in the forearm.
