NARIZ.

Escrito por Dr. Jesús García Ruiz

Nasi: estructura del aparato respiratorio formada por la pirámide nasal y las cavidades nasales y que contiene el órgano olfatorio.

<(F.): Nez: est la saillie médiane du visage située au-dessus de la lèvre supérieure et qui, en le surplombant, recouvre l'orifice des fosses nasales, qui constituent le segment supérieur des voies respiratoires et renferment l'organe de l'olfaction. Il concourt, en livrant passage à l'air, à l'accomplissement de la respiration et de la phonation.

<(In.): Nose: the specialized structure of the face that serves both as the organ of smell and as a means of bringing air into the lungs. The nostrils, which form the external entrance of the nose, lead into the two nasal cavities, which are separated from each other by the nasal septum, a partition formed of cartilage and bone. Three bony ridges project from the outer wall of each nasal cavity and partially divide the cavity into three air passages. At the back of the nose these passages lead into the pharynx. The passages also are connected by openings with the paranasal sinuses. One of the functions of the nose is to drain fluids discharged from the sinuses. The nasal cavities also have a connection with the ears by the eustachian tubes, and with the region of the eyes by the nasolacrimal ducts.
