Hand bones
The hand bones (lat. Ossa manus) are divided into the carpal bones, metacarpal bones and phalanges. There are eight carpal bones, five metacarpals and 14 phalanges. These 27 bones form the bony support of the hand.
Anatomy
The bones of the hand can be divided into different parts: the fingers (digiti manus), the metacarpus and the carpus. The palm of the hand is called palma manus. The back of the hand is called dorsum manus. The hand is oriented as follows. The little finger is directed towards the ulna, the thumb towards the radius.
In total, the hand consists of 27 individual bones. 14 bones belong to the fingers, 5 bones to the metacarpus and 8 bones to the carpus.
The proximal wrist is formed by the proximal carpal bones and the bones of the forearm. The distal wrist is formed between the two rows of carpal bones. The metacarpal and interphalangeal joints are located between the metacarpals and the respective phalanges, but also between the individual bones of the fingers.
Function
The hand bones serve as support for the hand. Many muscles are attached to the bones, making the movement of the hand possible.
