Are sudoriferous glands considered part of the philosebaceous unit?

Sudoriferous glands, also known as sweat glands, are not considered part of the philosebaceous unit. The philosebaceous unit is primarily made up of hair follicles, sebaceous glands, and associated structures that contribute to the health and function of hair. Sebaceous glands produce sebum, which helps to lubricate both the hair and skin, while the hair follicle houses the hair strand itself.

Sudoriferous glands serve a different function—they are involved in thermoregulation and waste excretion through the secretion of sweat. Their role is distinct from that of the sebaceous glands and hair follicles, which collectively form the philosebaceous unit. This separation of functions underlines why sudoriferous glands are not classified as part of this specific anatomical and functional unit.
