Artery Collateral Large

The large collateral artery (a. collateralis magna) is a large artery that is located in the neck and head. It is a branch of the common carotid artery and passes through the neck and head. The main function of this artery is to supply blood to the brain, as well as the muscles and organs of the neck.

The great collateral artery has several branches that pass through different areas of the head and neck. One of the main branches is the posterior inferior cerebral artery (a. cerebri posterior inferior). It passes through the occipital lobe of the brain and supplies blood to the posterior parts of the brain.

In addition, the great collateral artery supplies blood to the muscles of the neck, including the muscles of the tongue, larynx and pharynx. This is important to maintain the normal functioning of these organs and prevent damage.

Diseases associated with the great collateral artery can lead to disruption of blood supply to the brain and other organs. For example, with atherosclerosis (a disease associated with the formation of plaques on the walls of the arteries), narrowing or blockage of the great collateral artery may occur. This can lead to decreased blood supply to the brain and other complications.

Overall, the great collateral artery plays an important role in maintaining normal functioning of the brain and neck. Therefore, it is important to monitor her condition and prevent possible diseases.
