Let’s start with an overview of carpal bone anatomy. The carpal bones refer to eight bones in your wrist. They are divided into two rows – proximal and distal – with each row comprised of 4 bones each. In terms of the carpal bone names, on the proximal row we find: And one the distal row, we find:
Collectively referred to as the carpus, they individually articulate with the long bones in the lower arm radius and ulna, as well as the metacarpals, to make up the wrist joint. There are eight carpal bones in the human wrist, each one being named according to their shape: The capitate is the largest of all the carpal bones .
The carpus is the anatomical term for the wrist which connects the radius and ulna of the forearm with the metacarpal bones of the hand. It is comprised of eight individual carpal bones that are seated in two neat rows of four. The proximal row of carpal bones, as seen in a lateral to medial direction on the palmar surface, include:
