Do you want to know what the bones of the hands are called? The truth is that in each hand there are almost thirty bones of the total human skeleton. Likewise, these bones require mobile joints to be able to perform movements with dexterity. It should be noted that the hand is divided into three parts to describe its bones and that is precisely what we explain in this article about what the bones of the hand are called. he bones of the hand.
The total number of bones in the hand is 27 and these are divided into:
- Bones of the wrist or carpus
- Bones of the palm or metacarpus
- Finger or digital bones
In addition to the skeleton, the hands also require a set of muscles and ligaments to achieve all of the movements.
Wrist bones
The bones of the wrist, also called carpal or carpal bones, are eight and are arranged in two rows or groups:
- Bones of the distal row: trapezius, trapezoid, large and hamate. In the image of step 1, you can locate them with the numbers 1, 2, 3 and 4.
- Bones of the proximal row: pisiform, pyramidal, lunate and scaphoid. They correspond to 5, 6, 7 and 8 in the image.
The carpus is embedded in a small cavity that is formed by the bones of the forearm, that is, the ulna and the radius, although in reality the ulna is not articulated with any of the bones of the wrist.
Bones of the palm of the hand
As for the bones of the palm of the hand, metacarpus or metacarpals, they can also be divided according to their location, that is, the finger to which they correspond ordered from the thumb outwards:
- First metacarpal
- Second metacarpal
- Third metacarpal
- Fourth metacarpal
- Fifth metacarpal
Bones of the fingers of the hand
The fingers of the hands or digital are called phalanges and each of the fingers has three phalanges, except for the thumb, which has two:
- Proximal phalanges: located at the base of the finger, in the part known as the knuckles.
- Middle phalanges: non-existent on the thumb, they are located between the proximal and distal ones.
- Distal phalanges: located at the end of the fingers.
