beginning
The abductor pollicis muscle is an important muscle that moves the thumb outward, and is also called “boshigatenkin.” This muscle group includes abductor pollicis longus (abductor pollicis longus) and abductor pollicis brevis (abductor pollicis brevis) muscle short (abductor pollicis brevis), and each acts on the base of the thumb and the first carpal bone. Blood supply is mainly carried out through the lower arm artery (radial artery), and normal function of this muscle is important for maintaining hand health.

What is the abductor pollicis muscle
The abductor pollicis muscle is an essential muscle for improving the maneuverability and functionality of the thumb. We can perform complex movements in our daily lives, such as grasping objects and writing letters. It supports the free movement of the thumb and greatly improves hand functionality.
How to read the abductor pollicis
It is read as “boshigatenkin,” and it indicates a muscle that has the power to move the thumb (thumb) outward.
Characteristics of the abductor pollicis muscle
The thumb is a very special part of the human hand, and its constituent bones are different from other fingers and enable a variety of movements. The abductor thumb muscle plays an important role as a muscle that supports the movement of the thumb to open outward, that is, abduction.
Location/position of the abductor pollicis
The abductor pollicis muscle starts between the arm's radius and ulna, and connects to the base of the thumb's base bone. There are abductors long and abductors short, and abductor pollicis longus and abductors short contribute to thumb abduction, and they support the thumb's range of motion by inserting them into different parts.
How to remember the abductor pollicis muscle
By combining “thumb = thumb” and “abduction = movement outward,” it means “the muscle that moves the thumb outward.” Remembering abduction with “A” in the vowel “aiueo” is the key point of how to memorize.
English/Latin for abductor pollicis
It is expressed as “Abdominal Pollicis Longus” and “Abdominal Pollicis Brevis” in English, and “Longus” and “Brevis” are also used in Latin to indicate the abductor muscles of the “long” and “short” thumbs, respectively.
Trivia about the abductor pollicis
In the evolution of the human body, the ability of the thumb to rotate was extremely important for humans to master tools. This ability, which is different from other animals, has influenced the development of human culture and technology.
Next, I will explain how the abductor thumb muscle receives nutrients and maintains its function. The abductor pollicis muscle plays a critical role in moving the thumb of the hand. The health of this muscle has a direct impact on various actions in daily life, so understanding how its blood supply works is important.
Tissues associated with the abductor pollicis muscle: features of blood supply
The blood supply to the abductor pollicis muscle is mainly carried out by the lower arm artery (radial artery). The lower brachial artery is an important blood vessel that supplies blood to many areas of the hand and arm, particularly the wrist joint and hand muscles. Blood flow to this area is closely related to the amount of activity in the abductor pollicis muscle, as it fluctuates in response to hand movement and position.
Tissues associated with the abductor pollicis muscle: location and location of blood supply
The deep flexion artery of the forearm, which is the blood supply source for the abductor pollicis muscle, passes through the inside of the forearm and branches to the palmar lateral branch near the base of the abductor pollicis muscle. Along with other muscles that support the movement of the thumb, it runs vertically on the inside of the abductor thumb muscle. This arrangement of blood supply ensures stable blood flow as the muscles contract and the thumb moves outward.
Tissues associated with the abductor pollicis muscle: blood supply trivia
Blood circulation to the abductor pollicis muscle is essential for muscle growth, repair, and maintenance of daily function. In particular, when performing advanced operations or precision work, the normal function of this muscle holds the key.
Even with relatively small muscles such as the abductor pollicis muscle, the risk of fatigue and injury increases if sufficient blood flow is not ensured. Cold hands and fingers may be a sign of this decrease in blood flow. Regular hand exercises promote blood supply to the abductor thumb muscle and maintain muscle health. In particular, stretching and strength training using the thumb are effective.
Abductor pollicis quiz and correct answers
Q: Which movements are the abductors of the thumb responsible for?
1. Finger bending motion
2. The movement of stretching a finger
3. Movement of moving the thumb outward
4. Movement of moving the thumb inward
A: 3. Movement of moving the thumb outward
Correct answer: 3
As the name suggests, the abductor thumb makes it possible to move the thumb outward.
summary
This time, I explained the location and location of the “abductor pollicis maximus muscle”, how to memorize it, and the English/Latin notation.
