MICROANATOMY

Detailed explanation-1: -Sebaceous glands develop on or near your hair follicles in the second layer of your skin (dermis). You have thousands of sebaceous glands all over your body. The only place where you don’t have sebaceous glands are on the palms of your hands and the soles of your feet.

Detailed explanation-2: -The sebaceous gland contributes the vast majority of skin surface lipids via its main product, sebum, which helps to seal in moisture and prevent desiccation of the skin. Because sebaceous glands empty into the hair canal, sebum mostly escapes onto the skin surface via a wicking action involving the hair shaft.

Detailed explanation-3: -Sebaceous glands are made up of lobules and ducts and true exocrine glands found in all areas of the skin except for the palms, soles, lip, and tops of the feet. The lobules are made up of sebocytes that produce sebum, a fatty material that lubricates hair and has bactericidal and fungicidal properties.

Detailed explanation-4: -Eccrine sweat glands first appear on the palms and soles during the fourth month of gestation; they become functional soon after birth. On the other hand, apocrine sweat glands do not function until hormonal stimulation during puberty.
