Bones of the Hand - MedG

 The hand is divided into three main sections: Carpals, Metacarpals, and Phalanges.

1. Carpal Bones (Wrist Bones):

   • There are 8 carpal bones, arranged in two rows:

     • Proximal row (1–4): closer to the forearm.

     • Distal row (5–8): closer to the palm.

   • They form the Carpometacarpal joint with the metacarpals.

2. Metacarpals (Palm Bones):

   • There are 5 metacarpal bones, each connecting the carpals to the fingers.

   • The joints between metacarpals and phalanges are called Metacarpophalangeal joints.

3. Phalanges (Finger Bones):

   • Each finger has 3 phalanges — proximal, middle, and distal — except the thumb, which has only 2 (proximal and distal).

   • Joints include:

     • Proximal Interphalangeal Joint (PIP)

     • Distal Interphalangeal Joint (DIP)
