In this article, I will explain the “extensor generalis muscle” in detail.
The extensor finger muscle is a muscle located on the dorsal side of the hand and is mainly responsible for finger extension. We'll dive deep into the structure, function, and exercises involved, and even touch on the symptoms seen when the extensor generalis muscle weakens and specific ways to strengthen and protect it. From knowledge useful for injury prevention and rehabilitation to maintaining daily health, we will shed light on this important muscle group from a multifaceted perspective. Please use this article to deepen your understanding of the body.

What is extensor finger muscle
The extensor finger muscle is one of the important muscles that support human hand movements, and has the function of moving the wrist and stretching the fingers. It is frequently used in everyday activities to enable easy hand use and detailed movements.
How to read extensor pollicis
The pronunciation is “soshi shinkin.” As the name suggests, it has the function of stretching the fingers of the hand.
Characteristics of extensor quadratus muscle
The extensor finger muscle is located specifically on the dorsal side of the hand and acts as an extensor from the wrist to the fingertips. In particular, it plays an important role in enabling precise finger movement by cooperating with other muscles.
Location/position of extensor finger muscles
The extensor finger muscle is located on the dorsal side of the forearm, and if you look at the human anatomy chart, it starts near the wrist and connects to the finger bones of the hand. It is important to grasp specific positions and muscle movements through human anatomy diagrams.
How to memorize extensor pollicis
As a way to remember the extensor generalis muscle, it's a good idea to remember it as a muscle group that stands out when you stretch your hand toward the back. By feeling which muscles are moving while moving your wrist, you can consciously learn the extensor generalis muscle.
English and Latin for extensor quadratus muscle
It is called “Extensor Digitorum” in English, and similar expressions are used in Latin. The literal translation means “one who stretches out his fingers,” and it accurately represents muscle function.
Trivia about extensor finger muscles
The extensor finger muscle is a muscle that attracts particular attention in stretching and rehabilitation to improve blood circulation in the hands. Also, it is a very important muscle for people in occupations that require fine hand movements, such as pianists and typists.
Tissue associated with extensor finger muscle: musculoabdominal characteristics
The abdominal muscle of the extensor pollicus muscle is located on the back of the arm and is connected to a tendon on the back side of the hand. Abdominal muscles are the thickest part of the muscles, and they are the main parts that exert strength. As a characteristic, since it belongs to the extensor muscle group, it has an important function that enables the movement of stretching the fingers. Also, the extensor muscles in the abdomen are generally tight, and they develop as you use them actively. Since the extensor finger muscle has the function of extending all fingers, its abdominal muscles play a very important role in maintaining hand function.
Tissue associated with extensor finger muscle: muscular abdominal location/position
The abdominal muscle of the extensor quadratus muscle is located between the humerus bone on the outside of the arm and the elbow, that is, in the dorsal (dorsal) part of the forearm. This muscle extends from the arm to the wrist, and is divided into multiple tendons near the wrist, and each connects to a finger on the back of the hand. In particular, in the forearm area, where muscle and abdominal restraint is less, the muscles are designed to be easy to move, providing moderate flexibility and strength to achieve fine finger movements.
Tissues associated with extensor finger muscles: trivia about muscle and abdominal muscles
An interesting trivia about extensor pollicis muscle is that this muscle not only stretches the finger, but is also involved in the movement of stretching the wrist. More specifically, the extensor finger muscle also plays a role in stabilizing the wrist, and its importance is particularly evident when grasping objects or performing detailed work using hands. Also, in past research, it has been pointed out that specific repetitive movements, such as using a keyboard or mouse, place excessive strain on the extensor finger muscles, and this has had an impact on research in the fields of occupational disabilities and rehabilitation.
Through this article, I think you were able to understand that the extensor finger muscle is not simply one of the muscles for moving the fingers, but plays a central role in hand function. By knowing the characteristics, position, and trivia of abdominal muscles, you can understand how important the fine balance of the human body is, and you can use it for daily life and care during exercise.
