Interphalangeal joint

The joints between the phalanges, including distal and proximal interphalangeal joints.

Metacarpophalangeal joint

The joint between the metacarpals and the proximal phalanges.

Carpometacarpal joint

The joint between the carpal bones and metacarpals, allowing movement of the wrist.

Ulnar styloid process

A bony prominence on the distal end of the ulna, located on the wrist.

Radial styloid process
