Olfactory communication is common in all animals and recent studies have shown that humans have this communication trait as well. This kind of ...
Sebaceous glands line the human skin while apocrine glands are located around body hairs. [1] Compared to other primates, humans have extensive axillary hair and have many odor producing sources, in particular many apocrine glands. [18] In humans, the apocrine glands have the ability to secrete pheromones. These steroid compounds are produced ...
There are three types of sweat glands: eccrine, apocrine, and apoeccrine. [1] Apocrine glands are primarily responsible for body malodor and, along with apoeccrine glands, are mostly expressed in the axillary (underarm) regions, whereas eccrine glands are distributed throughout virtually all of the rest of the skin in the body, although they are also particularly expressed in the axillary ...
