Do you want to know what name the hand bones? The truth is that almost thirty bones of the total human skeleton are located in each hand. 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 to you in this OneHowTo article about what are the bones of the hand called.
The 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
- Palm bones or metacarpus
- Finger or digital bones
In addition to the skeleton, the hands also require a set of muscles and ligaments to achieve all 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:
- Distal row bones: trapezoid, trapezoid, large and hooked. In the image of step 1, you can locate them with the numbers 1, 2, 3 and 4.
- Proximal row bones: pisiform, pyramidal, lunate and scaphoid. They correspond to 5, 6, 7 and 8 in the image.
The carpus are 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.
Palm bones
As for the bones of the palm, metacarpus or metacarpals, they can also be divided according to their location, that is, the finger to which they correspond ordered from the thumb to the outside:
- First metacarpal
- Second metacarpal
- Third metacarpal
- Fourth metacarpal
- Fifth metacarpal
Bones of the fingers of the hand
The finger or digital fingers They 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: nonexistent on the thumb, they are located between the proximal and distal ones.
- Distal phalanges: located at the end of the fingers.
