Nasal sebum
Nasal sebum, also known as nose grease/oil, is a type of sebum that is specifically secreted in the nasal cavity. This type of sebum has a unique composition, different from the sebum secreted on the rest of the body. Nasal sebum is rich in squalene, a natural organic compound that is also a precursor for synthesis of steroids.
Composition[edit | edit source]
Nasal sebum is composed of a variety of substances, including triglycerides, fatty acids, wax esters, squalene, and cholesterol. The exact composition can vary depending on a variety of factors, including age, diet, and overall health.
Function[edit | edit source]
The primary function of nasal sebum is to protect and lubricate the nasal cavity. The sebum helps to keep the nasal passages moist, preventing them from drying out and becoming irritated. It also helps to trap and remove foreign particles and microorganisms, helping to prevent infection.
In addition to its protective functions, nasal sebum also plays a role in the sense of smell. The sebum helps to dissolve odor molecules, making them more easily detectable by the olfactory receptors in the nose.
Production and Regulation[edit | edit source]
Nasal sebum is produced by sebaceous glands located in the skin of the nasal cavity. The production of sebum is regulated by a variety of factors, including hormones such as androgens and estrogens, as well as diet and overall health.
Excessive production of nasal sebum can lead to a condition known as rhinorrhea, or a runny nose. This can be caused by a variety of factors, including allergies, colds, and other respiratory infections.
