What is the nasal mucosa?
nasal mucosa, also known as mucous membranes and respiratory mucosa, is tissue that lines the nasal cavity. The tissue consists of four layers. The mucosa is the first layer to provide a protective lining that captures bacteria to prevent infection. Pseudostratified column epithelium, basement membrane and lamina propria are the remaining layers that hold tissue cells, blood vessels and glands that produce protective slime.
The nasal mucosa is a wet tissue that excrete the mucosa. This lines of the nasal cavity line to capture bacteria and other materials that enter the nose. The nasal cavity is particularly susceptible to infection and other problems due to its environmental exposure. When people inhale through the nose, they not only introduce oxygen into the inner body, but also introduce any dirt or bacteria in the air that breathe the body to the vulnerability of exposed inner tissue. Other parts of the body with exposed tissues do the same. For example, ears exclude a strong wax mucosa,that catches the bacteria and protects the inner ear from infection. The mucous membrane produced in the nasal cavity is different and has a thinner consistency than the mucous membranes in the ear.
The first layer in the nasal mucosa under the mucous membrane is a pseudostratified column epithelium. There are many cup cells in the epithelium layer, which are described as a flask. Just below the epithelium is a basement membrane that serves as an anchor for epithelial cells. The lower layer of nasal cavity tissue under the basement membrane is propria laminate, which is full of blood vessels and seromucosal glands.
Another main function of the nasal mucosa is the condition of the air to enter the rest of the respiratory system. Part of this preparation includes capturing bacteria and other foreign particles in the mucous membrane, which is then forced to the back of the neck of the cili. Cilia are small, hair fibers that line the nasal cavity walls and protect tissue from infection. Nasal mucosaThe mucosa is not only used to remove bacteria from the air entering the respiratory system, but also moisturizes or adds moisture to the air. Another way to prepare the air for entering the respiratory system, the heat of heat radiating from the blood vessels into the lamina propria is to warm up.
Even with the mucosa lining, the nasal mucosa remains completely susceptible to infection and inflammation. When this tissue is infected, it is called rhinitis. Rhinitis is a general term that describes any condition that results in an infected and irritated lining of the nasal cavity. The most common cause of rhinitis is to communicate cold, but it can also be the result of allergies or other infections. The infected mucosa causes discharge, overload and swelling.
