Artery Nasal Posterior Common

The posterior common nasal artery (a. nasalis posterior communis) is one of the arteries that provides blood supply to the nasal cavity and surrounding tissues. It is a branch of the external carotid artery and passes through the nasal septum.

The common posterior nasal artery consists of two branches: superior and inferior. The superior branch arises from the external carotid artery in the pharynx and passes upward through the maxillary sinus, where it divides into two branches: superior and inferior. The inferior branch passes down through the lower jaw and enters the nasal cavity, where it branches into small vessels.

The main function of the posterior common nasal artery is to provide blood supply to the nasal cavity and its tissues. It is also involved in the nutrition of the teeth and gums of the upper jaw. In addition, the common nasal posterior artery can be damaged by injuries to the nose and upper jaw, which can lead to bleeding and other serious consequences.

Thus, the posterior common nasal artery is an important element of the human vascular system, which provides blood supply to important structures of the face and nasal cavity.
