Hand bones

from Wikipedia, the free encyclopedia
Bones of the hand
(from Gray's Anatomy )

The hand bones (lat. Ossa manus ) form the bony support of the hand or the forefoot. There are 27 hand bones in humans. They are divided into three groups:

Carpal bones ( Ossa carpi )

The eight carpal bones are in two rows of four bones each. They are therefore called carpal bones close to the body (proximal) and distal (distal).

The proximal carpal bones ( ossa carpi ) near the body include (starting on the thumb side outwards):

X-ray of a human hand. A scaphoid bone, B lunar bone, C triangular bone, D pea bone, E large polygonal bone, F small polygonal bone, G head bone, H hook bone

The distal carpal bones include (starting on the thumb side outwards):

The carpal bones can be remembered with the help of the following verse:

A barge that travels in the moon enschein
in the triangle around the pea bone .
Large polygon, small polygon ,
the head must be on the hook .

Metacarpal bone (metacarpal bone)

The metacarpal bones are called the metacarpals IV ( primum, secundum, tertium, quartum, quintum ) beginning on the thumb side .

Finger bones (Ossa digitorum manus)

The finger bones are divided into the following bones:

  • Phalanx proximalis IV (finger bones close to the body, phalanx , towards the wrist)
  • Phalanx media II-V (middle finger bone)
  • Phalanx distalis IV (finger bone distant from the body, phalanx ).

The middle phalanx of the middle finger is referred to as the phalanx media III . The thumb consists of only two limbs, the proximal and distal phalanges.
