Nasal Branches Posterior Inferior

Of course, I can write an article about the nasal branches of the posterior inferior (lateral) greater palatine nerve, which belongs to the Latin nomenclature PNA and BNA and is designated as nrami nasaresis posteriorie inferiorie laterales. First let's look at the anatomical structure of this nerve.

The nasal branches of the posterior inferior greater nasal nerves (PNA, BNA) are branches of the greater palatine nerve. The Latin term “palatine” is associated with the process of human birth and development, since the greater palate nerve originates from the third or fourth cervical vertebra. These branches run down and back, reaching the inferior nasal opening.

The anatomical structure of the nose is very individual and unique for each person. The greater nasal nerve supplies the mucous membrane of the posterior nasal septum, lower nostril, floor of the nose, etc. It also supplies the upper skin of the side of the face.

The functions of this branch are huge and varied. For example, it is involved in the sense of the position of the mouth and nose, smell, breathing and laughter, taste and hearing. In addition, the major nasal nerves serve as a stimulator for the formation of the bone sound of the voice.

The nasal branches of the posterior inferior palate are a set of nerves that provide innervation to the posterior wall and floor of the nasal cavity. These branches are part of the posterior division of the oculonasal nerve and can be either lateral or medial. They arise from the pterygopalatine nerve ganglion and enter the posterior wall of the nose, where they form a network of neurons that provides innervation to the mucous membrane and muscles of the nose.

The lateral branch of the greater palate (p.n.a. lateralis sinus) is the largest branch of the posterior part of the greater palate and passes through the posterior upper part of the lateral wall of the nose. It is divided into horizontal branches and vertical branches. The former enter the mucous membrane of the bottom of the nose, and the latter connect to the neurons of the mucous membrane of the nasal root. The latter form a functional respiratory reflex, which is an important part of the functioning of the respiratory system.

The inferior posterior branch of the greater palate is the most delicate branch of this division. It enters the posterior wing of the main nasal septum and runs along the lower border, where it enters the horizontal muscles of the posterior aspect of the maxillary bone. This branch provides functional breathing along the cranial part of the greater palate, associated with the absorption of air through the nose.

The importance of these branches for the innervation of the nasal cavity is great, as they provide protection of the body from the external environment, the spread of viruses and bacteria, and other vital functions. Lack of innervation to the lower parts of the nose can lead to a variety of problems, including difficulty breathing, ulcers, swelling, pain, bleeding and other complications.
