Anatomy 101: Finger Bones

Bones-Metacarpals_Index

Did you know that there are 27 bones in the hand and wrist? The hand is a very complex anatomical structure. Fingers, also known as phalanges, have three bones each. The finger bones, as shown in the figure above, are:

  1. Proximal phalanges: Above the metacarpals, below the knuckle
  2. Middle phalanges: Just above the knuckle
  3. Distal phalanges: At the fingertip

The thumb mimics the other fingers but does not have a middle phalanx. Metacarpals are hand bones that line up with the fingers. They give the hand its structure and serve as an attachment for many small muscles, tendons and ligaments in the hand.
