The pisiform bone (also called pisiforme or lentiform bone) is a small knobbly, pea-shaped wrist bone. It forms the ulnar border of the carpal tunnel.
The pisiform bone is found in the proximal row of the carpus. It is located where the ulna (inner bone of the forearm when in anatomical position) joins the carpus (wrist). It articulates only with the triquetral.
It is a sesamoid bone.
The pisiform bone may be known by its small size, and by its presenting a single articular facet. It is situated on a plane anterior to the other carpal bones and is spheroidal in form.
The etymology derives from the Latin pīsum which means "pea".

Which carpal bone can be palpated as a projection distal to the styloid process of the ulna?
The styloid process of the Ulna (one of the bones of the forearm) is where the Ulna connects to the ligament of the wrist joint. The Triquetrum, Lunate and Pisiform carpal bones all lie distal to this. However the carpal bone most easily palpable is the Pisiform bone.

Which forearm bone allows us to rotate the wrist?
There are 8 small bones in wrist joint.Proximalrow contains (From lateral to medial side.) ScaphoidLunateTriquartal and Pisiform bones. Except Pisiform other three are attached to lower end of 'Radius' bone. Please note that in 'elbow' joint Ulna bone takes part and in wrist joint charge is handed over to Radius bone. Distal row contains Trapezium, Trapezoid, Capitate and Ham-mate. So if you ask about the single bone, then the answer is Radius and not Ulna bone. But please remember that 'single' bone can not form a joint. There has to be at-least two bones. Here lower end of Radius comes in contact with three bones. Scaphoid, Lunate and Triquartal bones. Pisiform is a sesmoid bone. On distal side there are carpal-metacarpal joints. There are 5 metacarpals attached to four carpal bones.
