Wrist bones anatomy. The radius articulates with the scaphoid laterally and the lunate medially. Your wrist is made up of eight small bones carpal bones plus two long bones in your forearm the radius and the ulna. The wrist connects the hand to the forearm.

The smaller bone the ulna is on the little finger side. It is relatively prone to injury. Before we discuss the movements of the wrist it is essential to describe.

The larger bone the radius is on the same side as the thumb. The carpals are arranged in two rows of four bones each. The bones comprising the wrist include the distal ends of the radius and ulna 8 carpal bones and the proximal portions of the 5 metacarpal bones see the images below.

Wrist anatomy wrist bones. Most of your wrist movement is between the carpal bones and the radius bone of the forearm but some gliding action occurs between carpal bones. Following are the carpal bones in the first row starting from the lateral side same side as your thumb.

This arrangement of bones allows for a wide range of movement. There are two long bones in the forearm that run from the elbow to the wrist. The wrist is a complex joint that bridges the hand to the forearm.

The wrist can bend straighten move laterally and rotate. It consists of the distal ends of the radius and ulna bones eight carpal bones and the proximal ends of five metacarpal bones.
