The cavities of the sinuses are lined with mucous membranes, or tissues, that look like the inside of your mouth. These membranes are smooth and shiny and made up of various distinct types of cells. First, a layer of goblet cells produce the mucus through tiny tubes, forming the mucous blanket. These goblet cells are interspersed between hair-like cells called ciliated columnar cells, which move the mucus across
the surface of the membrane (6). The membranes of all the sinuses are covered
with these ciliated columnar cells. Together, the mucous membranes, the ciliated columnar cells, and the mucus itself all protect the body by establishing a defense system in the upper airway, or the nose and the sinuses.
A base layer below the goblet cells and the ciliated columnar cells is formed by basal cells. These cells form the barrier preventing infection and toxins from entering the body through the sinuses. The basal lining is a defense shield for the body in the same way that your skin protects your insides from foreign substances.
The brain relies on the sinuses in various ways as well. Aside from providing clean, oxygen-rich air to the brain via the bloodstream, the sinuses aid the brain in several autonomi

The nose is the upper most structure of the respiratory system and can be thought of as the portal to the lungs. Air can enter the body only through the nose or the mouth. In a hea
Beyond mere breathing and mucus production, the nose is integrally connected to the functioning of the rest of the body. One important factor is our sense of smell. The cribriform
After passing through the nasopharynx, mucus is swallowed, dropping into the throat (pharynx) and behind the voice box through the esophagus and finally into the stomach (1). The a
As I already noted, the ear is connected to the sinuses through the eu - stachian tube. When the sinuses are inflamed, the eustachian tubes also become inflamed. Infections in the
