Ulnar Artery

The Ulnar Artery is one of the most important arteries of the upper limb. It is a branch of the brachial artery and departs from it in the cubital fossa. Passing through the ulnar groove, the ulnar artery reaches the wrist joint, where it passes to the palm and forms the superficial palmar arch.

Blood flowing through the ulnar artery provides blood supply to the joints, skin and muscles of the forearm and hand. In particular, the ulnar artery is responsible for supplying blood to the following muscles: finger flexor muscles, wrist flexor muscles, wrist flexor muscles, elbow flexor muscles and many others.

It is important to note that the ulnar artery anastomoses with the superficial palmar branch of the radial artery, thus forming additional blood flow pathways. This is an important factor in maintaining blood supply to the upper limb even in the presence of problems with the main arteries.

There are various diseases that can affect the functioning of the ulnar artery. For example, atherosclerosis, thrombosis, embolism and other diseases can lead to impaired blood flow. This can lead to serious consequences such as ischemia and infarction of the upper limb.

Overall, the ulnar artery is an important part of the circulation of the upper extremity, providing blood supply to many important muscles and joints. Therefore, any problems with its functioning should be immediately examined and treated by a doctor to prevent serious consequences.

The ulnar artery is one of the main arteries of the forearm, which provides blood supply to the joints, skin and muscles of the forearm and hand. This artery is a branch of the brachial artery and arises from it in the cubital fossa. From there it runs in the ulnar groove to the wrist joint, and then passes to the palm, where it forms the superficial palmar arch.

In the ulnar groove, the ulnar artery is located between the ulna bone and the muscles of the forearm. Here it is divided into several branches, which provide blood supply to the joints and muscles of the forearm. One of the branches of the ulnar artery runs along the wrist joint and anastomoses with the superficial palmar branch of the radial artery, forming the superficial palmar arch. This arch is an important site of blood supply to the skin and muscles of the palm.

The ulnar artery is an important artery of the upper limb, which provides blood supply to the hand and forearm. In addition, it also plays an important role in the blood supply to the joints of the elbow and wrist. In case of disruption of the blood supply to the Ulnar artery, various diseases are possible, such as thrombosis or embolism, which can lead to disruption of blood supply in the relevant areas.

In general, the ulnar artery is an important component of the circulation of the upper limb. It supplies blood to the joints, skin and muscles of the forearm and hand, and is an important artery for maintaining the health of the upper limb.

**Ulnar arteries** (Latin *arteria ulnaris*) are branches of the brachial artery, forming, among other branches, the *ulnar canal*, through which they pass all the way to the arterial network of the palm.

**Arteries originating from a. brachialis under the name of the median artery supplies** the auricle, middle ear, nasal cavity, upper teeth, upper lip, orbit and gum of the anterior upper jaw.
