Apocrine (/ ˈ æ p ə k r ɪ n /) [1] is a term used to classify the mode of secretion of exocrine glands. In apocrine secretion, secretory cells accumulate material at their apical ends, often forming blebs or "snouts", and this material then buds off from the cells, forming extracellular vesicles .
An apocrine sweat gland (/ ˈ æ p ə k r ə n,-ˌ k r aɪ n,-ˌ k r iː n /; from Greek apo 'away' and krinein 'to separate') [5] [6] is composed of a coiled secretory portion located at the junction of the dermis and subcutaneous fat, from which a straight portion inserts and secretes into the infundibular portion of the hair follicle. [7]
In apocrine secretion (pictured), portions of the cell are pinched off and later disintegrate. Both apocrine and eccrine sweat glands use merocrine secretion, where vesicles in the gland release sweat via exocytosis, leaving the entire cell intact.
Apocrine sweat glands are restricted to the armpits and a few other areas of the body and produce an odorless, oily, opaque secretion which then gains its characteristic odor from bacterial decomposition. In humans, sweating is primarily a means of thermoregulation, which is achieved by the water-rich secretion of the eccrine glands. Maximum ...
Depending on how their products are secreted, exocrine glands are categorized as merocrine, apocrine, or holocrine. [ 1 ] Merocrine – the cells of the gland excrete their substances by exocytosis into a duct; for example, pancreatic acinar cells, eccrine sweat glands [ dubious – discuss ] , salivary glands , goblet cells , intestinal glands ...
Here they produce cerumen, or earwax, by mixing their secretion with sebum and dead epidermal cells. Cerumen keeps the eardrum pliable, lubricates and cleans the external auditory canal , waterproofs the canal, kills bacteria, and serves as a barrier to trap foreign particles (dust, fungal spores, etc.) by coating the guard hairs of the ear ...
Nguyen explained that body odor is primarily associated with apocrine sweat glands, found in the armpit and groin areas. For those without the mutation in the ABCC11 gene, protein in those sweat ...
Apocrine glands – a portion of the secreting cell's body is lost during secretion. The term Apocrine gland is often used to refer to the apocrine sweat glands, however it is thought that apocrine sweat glands may not be true apocrine glands as they may not use the apocrine method of secretion. (e.g. mammary gland, sweat gland of arm pit ...
