Sebaceous Glands: Only one type of sebaceous glands are found in the skin. Eccrine-gland sweat allows the body to control its internal temperature in response to thermal stress. The apocrine sweat glands produce a more viscid sweat than the eccrine glands because it contains fatty compounds. The two types of sweat glands are the apocrine and eccrine sweat glands. They are smaller than apocrine sweat glands, and they do not extend as far into the dermis. Another type of gland (eccrine gland or simple sweat gland) produces most sweat. The apocrine sweat is released around the hair follicle and is believed to moisturize the hair follicle like sebum as well as impart a specific scent. Sebaceous Glands: Sebaceous glands secrete sebum. Apocrine glands open into the hair follicle, leading to the surface of the skin. Eccrine-gland sweat allows the body to control its internal temperature in response to thermal stress. eccrine sweat glands are located deeper in the dermis than apocrine sweat glands. These glands release a heavier, fat-laden sweat that carries a distinct odor. The NCL‐SG3 cell line is the only available immortalized human eccrine sweat gland cell line and, despite its drawbacks, continues to provide new information on cell signalling in eccrine gland function; for example, oxytocin, 90 oestrogen, 93 galanin 94 and PAR‐2 receptor activation 95 all influence sweat gland cell function.
