Artery Connecting Posterior

The communicating artery Posterior (a. Communicans Posterior) is an artery that connects the posterior ends of the internal carotid arteries and vertebral arteries. It is a continuation of the posterior communicating artery, which is located at the back of the base of the skull.

The posterior communicating artery begins from the posterior border of the internal carotid artery and passes along the posterior surface of the skull, where it connects with the vertebral arteries. This artery has a length of about 3-5 cm and a diameter of about 2 mm.

The function of the communicating posterior artery is to provide blood supply to the posterior part of the brain and cerebellum. In addition, it may participate in the blood supply to the posterior wall of the skull and spinal nerves.

The importance of the posterior communicating artery lies in the fact that its disruption can lead to various diseases such as stroke, cerebral infarction or cerebrovascular accident. Therefore, it is important to know the anatomy and function of this artery to avoid possible complications.

In general, the communicating posterior artery is an important artery in the human body, which plays an important role in providing blood supply to the posterior part of the brain.

The arterial communicant is part of the posterior aorta. It provides communication between the right and left branches of the aorta, and also contains a continuation of the right subclavian artery, which begins in the thoracic part of the aorta.\n\nBetween the mesentery of the spleen and the mesentery of the small intestine, the arterial communicant enters the lumbar flexure of the organ, and is then distributed throughout the duodenum and jejunum. Visceral branches are arterial vascular bundles that supply the liver, pancreas and the walls of the stomach and intestines.\n\nThe abdominal peritoneal branch drains blood from the anterior abdominal wall and emerges as a dorsal branch onto the abdominal wall. The inferior phrenic branch supplies the diaphragm\n\nThe venous branches of the arterial communication extend along the anterior and posterior median canals. These include the right and left internal intercostal veins, which pass under the costal cushion.

The arteriological communication is a very important vascular device in the physiology of the human body. It allows for sufficient blood flow to the tissues and organs of the abdominal cavity, especially those that require large amounts of oxygen and nutrients. Arterial communication is also involved in the processes of metabolism and cell regeneration in the human body.
