Function of Sebaceous glands (Oil Glands)
Produce sebum Lubricates the skin surface
Sebaceous glands are specialized skin structures that are responsible for producing sebum, an oily substance that acts as a lubricant and protects the skin from dehydration. The primary function of sebaceous glands is to produce and secrete sebum, which helps to moisturize and protect the skin.
Sebum is composed of a mixture of lipids, including triglycerides, wax esters, squalene, and cholesterol. These lipids help to form a protective barrier on the surface of the skin, which helps to prevent excessive water loss.
Sebaceous glands are found throughout the skin, with the highest concentration on the face, scalp, and upper back. They are connected to hair follicles, and the sebum produced by these glands is released onto the skin through the hair follicle opening.
Sebaceous glands also play a role in regulating body temperature. When the body becomes overheated, sebaceous glands produce sweat, which helps to cool the skin and regulate body temperature.
While sebum is important for protecting and moisturizing the skin, excessive production of sebum can lead to skin problems such as acne. Acne occurs when pores become clogged with excess sebum, dead skin cells, and bacteria, leading to inflammation and the formation of pimples.
