Phalanges (Finger Bones)
The phalanges are the bones of the fingers and thumb — 14 in each hand. Each finger has three and the thumb has two, giving the hand its remarkable dexterity.
What it is
The phalanges are the small long bones of the digits: three in each finger and two in the thumb.
Where it is
The fingers and thumb.
What it does
Allow the fine, precise movements of the fingers and thumb that underpin gripping, pinching and manipulating objects.
Connections
Joints and connections

- Mallet finger (an injury to the tendon at the fingertip)
- Dislocated finger joint
Education and reference only. This explains the anatomy in plain terms; it is not a diagnosis. A severe injury, a visibly deformed limb, or the inability to move or bear weight needs urgent assessment — call 999 or go to A&E for a serious injury.
Did you know?
An interesting fact
The human thumb has only two phalanges while each finger has three — part of what makes the opposable thumb so versatile.
