Briefly discuss about ulna and radius. physical education​

Answer 1

Answer:

The radius and ulna are the bones of the forearm. The forearm is the region of the upper limb that extends from the elbow to the wrist. The radius bone (os radius) supports the lateral (thumb) side of the forearm and the. ulna bone (os ulna) supports the medial (little finger) side.

The radius allows for movement of the arms and especially provides for the full range of motion of the hand and wrist. 3 The radius and ulna work together to provide leverage for lifting and rotation for manipulation of objects

The radius articulates with the ulna in a synovial pivot joint. The radial head rotates within the annular ligament and radial notch on the ulna to produce pronation of the forearm. The radius and ulna also articulate distally in reverse to their articulation at the elbow to produce supination.
