Pisiform Bone
The structure indicated is the
pisiform bone of the hand. There are
three groups of bones in the hand:
- Carpal bones (8 in total)
- Metacarpal bones
- Phalanges
The carpal bones are separated into
two rows:
- Proximal row
- Distal row
The pisiform bone is one of
four bones in the proximal row of carpals (
scaphoid, lunate, triquetral, pisiform). The pisiform bone is a tiny
sesamoid bone located in the tendon of the
flexor carpi ulnaris muscle. It articulates with the palmar surface of the
triquetral bone. Learn more about the anatomy of the
bones of the hand in this tutorial.
