Sebum is secreted into hair follicles by sebaceous glands. Sebum is an oil that protects the skin from outside elements and keeps it nice and moist.
The numerous varieties of hair that can be found on the body are produced by the hair follicles.
<h3>What gland is referred to as sebaceous?</h3>
Sebaceous glands are tiny oil-producing glands found in mammal skin. Typically linked to hair follicles, sebaceous glands secrete a fatty substance called sebum into the follicular duct, which subsequently travels to the skin's surface.
<h3>What are the sebaceous glands used for?</h3>
- Sebum is a complex mixture of oils that includes triglycerides and products of fatty acid breakdown, wax esters, squalene, cholesterol esters, and cholesterol.
- The typical function of sebaceous glands is to create and secrete sebum.
