GENERAL HISTOLOGY

Detailed explanation-1: -Sebaceous glands produce an oily substance called sebum and sweat glands produce a watery substance called sweat. Sweat glands have ducts, which are pathways to excrete substances to the surface of your skin. Sebaceous glands secrete sebum through your hair follicles and don’t have ducts.

Detailed explanation-2: -The sebaceous glands produce an oily substance called sebum, which contributes the vast majority of lipids-fat molecules-to the skin’s surface. These surface lipids keep the skin hydrated and healthy. Having too much or too little sebum can cause skin problems.

Detailed explanation-3: -sebaceous gland, small oil-producing gland present in the skin of mammals. Sebaceous glands are usually attached to hair follicles and release a fatty substance, sebum, into the follicular duct and thence to the surface of the skin.

Detailed explanation-4: -Sebum production is under the control of sex hormones (androgens). The most active androgens are testosterone, 5-testosterone (DHT) and 5-androstene-317diol. These hormones and others are made by the sex glands (ovary in females, testis in males) and by the adrenal gland.
