Naris

Naris is a term used in anatomy to refer to the nostrils. It is derived from the Latin word 'naris', which means 'nostril'. The term is often used in the plural form, 'nares', to refer to both nostrils. The nares are the external part of the respiratory system, allowing the inhalation and exhalation of air.

Structure

The nares are located in the middle of the human face, at the base of the nose. They are separated by the nasal septum, a wall of cartilage and bone. Each naris is surrounded by the alar cartilage, which forms the shape of the nostril.

The inside of the nares is lined with mucous membrane, which helps to warm and moisten the air as it is inhaled. This membrane also contains tiny hairs called cilia, which help to filter out dust and other particles from the air.

Function

The primary function of the nares is to provide an entryway for air into the respiratory system. As air is inhaled, it passes through the nares and into the nasal cavity, where it is warmed and moistened before continuing to the lungs.

The nares also play a role in the sense of smell. The upper part of the nasal cavity contains the olfactory epithelium, a specialized tissue responsible for detecting odors. As air is inhaled through the nares, odor molecules are carried to the olfactory epithelium, where they are detected and interpreted by the brain.

Clinical significance

The nares can be affected by a variety of medical conditions, including allergies, sinusitis, and nasal polyps. Treatment for these conditions may involve medication, surgery, or other interventions.
