Upper limbs

4 May 2021

Consists of the Upper arm, the humerus bone forms the ball and socket joint of the shoulder with the clavicle and the scapula, and it also forms the elbow joint with the lower arm bones. 

The lower arm or the forearm consists of the radius and the ulna. The ulna, which is on the medial side of the forearm, forms a hinge joint with the humerus at the elbow. The radius gives the possibility for the forearm and hand to turn over at the wrist joint.

The lower arm bones form the wrist joints with the carpals, eight small bones that give flexibility to the wrist. The carpels connect to the five metacarpals and connect to each of the fingers. The bones in the fingers and thumbs are called phalanges, and apart from the thumb, which only has two bones, each finger has three. The thumb is made up of the proximal phalange and the distal phalange. The finger is made up of the proximal phalange, the middle phalange and the distal phalange.
