The scientific name for oil glands is sebaceous glands.
Sebaceous glands are small, oil-producing glands found in the skin of mammals. They are typically associated with hair follicles, and their primary function is to secrete an oily substance called sebum. Sebum is released into the hair follicle and then travels to the skin's surface, where it helps to lubricate and protect the skin and hair.
Here's a breakdown of key aspects:
- Function: The main function of sebaceous glands is to produce and secrete sebum.
- Composition of Sebum: Sebum is a complex mixture of lipids, including triglycerides, wax esters, squalene, and cholesterol.
- Location: Sebaceous glands are found throughout the body, except for the palms of the hands and soles of the feet. They are most abundant on the face, scalp, and upper torso.
- Association with Hair Follicles: Most sebaceous glands are connected to hair follicles, and sebum is secreted into the follicle. However, some sebaceous glands, such as those on the lips, eyelids (Meibomian glands), and genitals, are not associated with hair follicles.
- Regulation: The activity of sebaceous glands is primarily regulated by hormones, particularly androgens.
Sebaceous glands play a vital role in maintaining skin health and protecting it from the environment.
