Artery Finger Hand Dorsal

Artery Digital Hand Dorsal: Main aspects and functions

The dorsal digital artery of the hand (a. digitalis dorsalis manus) is an important anatomical structure that provides blood supply to the fingers of the upper limb. It is one of the branches of the carpal artery and plays a key role in supplying blood to the skin and tissue of the fingers.

The dorsal digital artery has two main sources: radial and ulnar. It usually arises from the radial artery running along the outer edge of the forearm, but in some cases it can arise from the ulnar artery. Once formed, it runs along the back of the wrist and runs along the fingers on the dorsal (back) side of the hand.

The dorsal digital artery is usually divided into four main branches, which pass between the bones of the fingers and branch in a network to provide blood supply to the fingers. These branches penetrate the tissues of the fingers and provide them with essential nutrients and oxygen.

The functional significance of the digital hand dorsal artery is to provide blood supply to the skin and tissues of the fingers, which is an important aspect for the normal functioning of the upper limb. The blood supply to the fingers ensures not only their vital activity, but also helps to perform various motor tasks, such as squeezing and unclenching objects, precision of movements, and so on.

As blood spreads through the fingers, the dorsal digital artery connects with other blood vessels in the digits, such as the palmar digital artery and digital arteries, forming a complex network of small vessels. This ensures effective blood flow throughout the entire structure of the fingers, ensuring their normal functioning.

However, like other arteries, the dorsal artery of the digital hand can also be subject to various pathological conditions. For example, blockage or stenosis (narrowing) of this artery can limit the blood supply to the fingers, which can cause problems with their function and health. In such cases, medical intervention may be required to restore normal blood flow.

In conclusion, the dorsal digital artery plays an important role in providing blood supply to the fingers of the upper limb. Its function is to provide sufficient blood and nutrients.

Artery Digital Hand Dorsal: Anatomy and Role in Blood Circulation

Introduction

Arteries play an important role in maintaining normal blood circulation in the body. One of the important arteries in the hand area is the dorsal artery of the digital hand (a. digitalis dorsalis manus). In this article we will look at the anatomy of this artery and its role in the circulation of the fingers.

Anatomy of the digital hand dorsal artery

The digital dorsal artery is one of the branches of the radial artery (a. radialis), which runs along the forearm. After passing under the radius, the radial artery enters the hand region and divides into several branches, including the dorsal artery of the digital hand.

The digital dorsal artery is located on the dorsal side of the hand, which means it is at the back of the hand compared to the palmar side. Numerous small branches arise from the dorsal artery of the finger, which provide blood supply to the fingers.

Role in circulation

The digital dorsal artery plays an important role in supplying blood to the fingers. Its branches penetrate the area between the fingers and form digital arches that nourish the skin, muscles and other tissues of the fingers.

The blood entering the dorsal artery of the finger contains oxygen and nutrients necessary to maintain normal cell function in the fingers. In addition, the artery is also responsible for draining waste blood and waste away from the cells of the fingers.

Pathologies and possible problems

Poor circulation in the fingers can be associated with a variety of pathologies, including atherosclerosis (deposition of fatty deposits on artery walls), thrombosis (formation of a blood clot in an artery), embolism (movement of a blood clot or other material through the circulatory system), and other conditions.

When the blood supply to the fingers is disrupted, various symptoms may occur, such as numbness, redness, swelling, soreness and loss of function of the fingers. In some cases, if circulatory problems are not corrected quickly enough, this can lead to necrosis (death) of finger tissue.

Conclusion

The dorsal artery of the digital hand plays an important role in providing blood circulation to the fingers. Its branches provide the necessary blood supply to maintain the normal function of the cells of the fingers, and also drain waste blood and waste from the cells. If problems occur with the dorsal artery of the digital hand, serious consequences can occur, including impaired sensitivity and functionality of the fingers.

It is important to pay attention to the state of your circulation and monitor the health of your arteries. Regular medical examinations and care for the cardiovascular system will help prevent the development of pathologies and maintain normal blood circulation in the fingers.
