Extensor of the Fingers of the Hand Deep

Extensor digitorum profundus: Anatomy, Functions and Role in Hand Movement

The deep digitorum extensor (Musculus extensor digitorum manus profundus) is a powerful muscle that is located on the back of the forearm and is responsible for extending the fingers. This muscle is important for hand motor skills, as it ensures the normal functioning of the hand and fingers.

Anatomy of the extensor digitorum profundus

The extensor digitorum profundus is one of the largest muscles in the forearm. It starts from the external epicondyle of the shoulder and the lower third of the posterior surface of the radius. The muscle then becomes a string, which passes through a channel in the hand and ends at the fingertips. All fifteen digital extensors, including the extensor digitorum profundus, pass through channels in the hand, which ensures their normal functioning.

Functions of the extensor digitorum profundus

The main function of the extensor digitorum profundus is to straighten the fingers. In addition, this muscle is also responsible for wrist extension and wrist flexion. Thanks to this muscle, the fingers can perform a variety of movements, such as squeezing and unclenching the hand, grasping and holding objects, and performing precise movements associated with writing or playing a musical instrument.

The role of the extensor digitorum profundus in arm movement

The extensor digitorum profundus plays an important role in the movement of the hands, as it ensures their normal functioning. This muscle works in tandem with the flexor digitorum, which is located on the front side of the forearm and is responsible for bending the fingers. Together they provide the precise coordination of hand and finger movements needed to perform many everyday tasks.

In conclusion, the extensor digitorum profundus is an important muscle that ensures the normal functioning of the hand and fingers. It plays a key role in arm movement and allows us to perform many everyday tasks. Therefore, it is important to pay attention to the health and training of these muscles to maintain their normal functioning throughout life.

The extensor digitorum is a group of muscles that are located on the back of the forearm and are responsible for straightening the fingers and wrist. However, there is also a deep extensor digitorum, which is located deep in the forearm. This muscle is one of the most powerful muscles in the forearm and plays an important role in maintaining hand stability and strength.

The extensor digitorum profundus consists of two heads: superficial and deep. The superficial head is located on the outside of the forearm, and the deep head is located under the skin, on the inside of the forearm. Both heads join together at the wrist, where they form a powerful tendon bundle that runs through the wrist and ends at the fingers.

The functions of the extensor digitorum profundus include extension of the thumb, index and middle fingers, and flexion of the little finger. It also helps maintain hand stability and strength while performing various activities such as writing, drawing, playing musical instruments, etc.

Training the deep digital extensor muscle can be achieved by performing exercises to strengthen the forearm muscles, such as dips, pull-ups, wrist and finger extension exercises. It is also important to avoid overusing or straining the muscles, as this can lead to injury and pain.
