The nasal cavity refers to the inside of the nose. It is a hollow space inside the nose and skull, which is surrounded with hairs and mucous membrane. The main function of the nasal cavity is to moisturize, warm, and filter the air getting inside the body before it gets inside the lungs.

The superior body of the nasal cavity is formed by four bones, that is, from anterior to posterior. These are:

1. Nasal

2. Frontal

3. Ethmoid (cribriform plate) and

4. Sphenoid (body)

Answer from: eri85

The superior border of the nasal cavity is formed by the structure

lamina kribriformis which separates the skull cavity from the nasal cavity.

Further Explanation

Anatomically, the nose is a protrusion in vertebrates containing nostrils, which filters the air for breathing. The nose is the most prominent part of the face, which functions to breathe breathing air, filter the air, warm the breathing air, also play a role in sound resonance.

The nose is a human sensory device that responds to stimuli in the form of odors or chemicals in the form of gases. Inside the nasal cavity, there are odorous nerve fibers that are equipped with small cells. Each scent cell has fine hairs (olfactory cilia) at the ends and is covered by mucous membranes that function as moisturizers for the nasal cavity.

The way the nose works is that, when we breathe, chemical substances in the form of gas come into the nose. The chemical which is the source of the odor will be dissolved in the mucous membranes, then it will stimulate fine hairs in the scent cells. smell cells will continue to stimulate this brain to be processed so they can find out the type of odor from these chemicals.

When the nose receives a disorder, it is usually caused by inflammation or runny nose that produces mucus or snot so that it prevents odor from reaching the nerve endings. Other disorders can also be caused by the presence of dirt on the nose and nose hair that is too much. Cleaning the nose from dirt and smoothing the hair, can help avoid the smell of smell.
