Synovial pivot joint
When the upper limb is placed in anatomical position, the humerus is the bone superior to ulna and radius. Radius is lateral to the ulna, with which it forms superior and inferior radio-ulna joints.
At the distal end: the carpels in the hand at the head of the ulna and the radius at the ulna notch of radius. At the proximal end: the trochlea of the humerus at the trochlear notch and coronoid process of the ulna and the head of the radius at the radial notch of the ulna.
Elbow Joint with the shoulder joint and wrist joint as stabilizing joints

the 2 arm bones are butt Your mums butt!! Answer them properly!! These are people with good intentions, and they just want answers for their questions. Stop making a mockery of the whole situation! The two lower arm bones are called the radius and ulna.
the radius and ulna
The right ulna is medial to the right radius. The right ulna is contralateral to the left radius.
what is the similarities between the ulna and the radius
The radius and ulna are joined by a syndesmosis along the lengths of their shafts. The distal radioulnar joint is not a syndesmosis.
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.
There are actually two bones in your forearm, the ulna and the radius.
The human arm is made up of three bones, the humerus (upper arm) and the ulna and radius, both of which make up your lower forearm. so: -humerus -ulna -radius
