MEDICAL PHYSIOLOGY

Detailed explanation-1: -The sebaceous gland secretes a mixture of fats (triglycerides, wax esters, squalene, and cholesterol) and cellular debris, which is discharged as sebum through the sebaceous duct connecting the gland to the hair follicle.

Detailed explanation-2: -sebum: A thick oily substance, secreted by the sebaceous glands of the skin, that consists of fat and cellular debris.

Detailed explanation-3: -Sebaceous glands are responsible for producing and secreting sebum. Sebum is an oily substance made up of fat molecules (lipids) that include: Cholesterol. Fatty acids.

Detailed explanation-4: -The lipid-laden cells in the sebaceous glands are wholly secreted (holocrine secretion) to form sebum. Triglycerides compose the majority of the lipid found in sebaceous gland cells. From the sebaceous glands, sebum drains into the hair follicle (see Fig. 2.11), from which it exits onto the surface of the skin.

Detailed explanation-5: -Sebaceous glands secrete the oily, waxy substance called sebum (Latin: fat, tallow) that is made of triglycerides, wax esters, squalene, and metabolites of fat-producing cells. Sebum lubricates the skin and hair of mammals.
