In this article, I will explain the “metacarpal bone” in detail.
The metacarpal bones are the five bones that make up the skeleton of the hand and play an important role in connecting the wrist and fingers. Each metacarpal bone corresponds to a different finger on the hand, and functions together with muscles and tendons to support various movements in everyday life. It is expressed as “Metacarpal bones” in English, and it is an essential part of the human body's structure and functionality. Please use this article to deepen your understanding of the body.

What is the metacarpal bone
The metacarpal bone is one of the bones that make up the human hand skeleton, and is located between the carpal bone (wrist bone) and the finger bone (phalanx). It is the foundation that supports hand function, and plays an essential role in various daily movements. The metacarpal bones are essential for understanding the structure of the hand.
How to read metacarpal
Metacarpal bones are read as “chushukotsu” in Japanese.
Characteristics of metacarpal bones
The metacarpal bone consists of 5 bones of different length and shape, and each corresponds to a different finger on the hand. These bones extend from the carpal bone and form the base of the finger by connecting to the phalanx. Also, many muscles and tendons are attached around the metacarpal bones, and they play an important role in supporting hand movements.
Location and position of the metacarpal bone
The metacarpal bone is located in the palm of the hand, and in the human anatomy diagram, it is depicted as 5 bones arranged between the carpal bones of the wrist and the phalanges of each finger in a schematic diagram of hand bones.
It is an important skeletal part following the basal bone, middle bone, and terminal bone that form the finger.
How to memorize metacarpal bones
When memorizing metacarpal bones, it is important that there are 5 fingers on the hand, and there is 1 metacarpal bone for each finger. Also, it is good to remember that it is the central bone that supports hand movement and is located between the carpal bone and phalanx bone.
English and Latin for metacarpal bones
In English, metacarpal bones are expressed as “Metacarpal Bones,” and in Latin, they are expressed as “Ossa Metacarpalia.”
Trivia about metacarpal bones
The metacarpal bones are closely linked to the diverse movements of the hand. For example, it is known that the metacarpal bones of pianists and typists evolve into unique shapes by repeating specific movements. Also, metacarpal fractures are common in sports, and prompt treatment is important.
Tissues associated with metacarpal bones: characteristics of the wrist (carpal bone)
The carpal bone is a general term for the 8 small bones in the wrist. Roughly divided into 2 rows, each bone allows for a variety of movements. The first column includes scaphoid bones, lunar bones, triangular bones, and bean-shaped bones, and the second column includes large rhomboid bones, small rhomboid bones, skulls, and phalanx bones. These carpal bones, along with the metacarpal bones (hand bones), form the basis of the hand's structure and provide flexible movement.
The characteristic of carpal bones is that each bone forms multiple joints, and wrist movements can be finely adjusted. This unique arrangement and structure allows human hands to perform detailed to powerful tasks.
Tissues related to metacarpal bones: location and position of wrist (carpal bone)
The wrist is located between the end of the forearm and the hand. The carpal bone is connected to the radius of the forearm and the part extending from the ulnar bone, and the metacarpal bone continues above it. The carpal bone smoothly rotates, bends, and stretches the wrist, and efficiently transfers force.
Wrist movements are extremely diverse, and mobility between carpal bones, between carpal bones and metacarpal bones, and between carpal bones and forearm bones realizes this. This mobility enables fine hand movements required in everyday life.
Tissues associated with metacarpal bones: wrist (carpal bone) trivia
Carpal tunnel syndrome is one of the diseases that cause wrist pain and discomfort. It occurs when nerves that pass through a narrow tunnel called a carpal tunnel are compressed. It often occurs due to excessive use or continuous use in a specific position.
Children's carpal bones are not fully developed when they are born. It forms gradually during the growth process and generally matures during adolescence.
If the carpal bone is damaged, rehabilitation is required. Depending on the extent of the damage, physical therapy, use of braces, and sometimes surgery may also be recommended. With proper treatment and rehabilitation, wrist function can often be restored.
Metacarpal bone quiz and correct answers
Q: What part of the hand is the metacarpal bone located in?
A: It is located in the palm of the hand, between the carpal bones and phalanges.
summary
This time, I explained the location and location of the “metacarpal bone,” how to memorize it, and the English and Latin notation.
How was it?
I would be happy if reading this article deepened my understanding of anatomy.
Learning is a long, never-ending journey, but I sincerely wish you all the best. Let's continue to study together and work hard for the national exam!
Please look forward to the next blog.
