: Unique to the axillary and perianal regions, these glands share features of both types but can secrete up to ten times more sweat than standard eccrine glands, playing a major role in heavy underarm sweating. Gland Function and Odor Production Apocrine Glands Function & Location - Cleveland Clinic
The armpit (axilla) is a unique area of the body containing a high concentration of specialized sweat glands. While they represent only about 2% of the body's total perspiration, they are the primary source of characteristic body odor due to their specific secretion types and interaction with skin bacteria. Anatomical Structure of Axillary Sweat Glands sweat gland armpit
: Distributed across nearly the entire body, these glands in the armpit secrete a clear, odorless, watery fluid directly onto the skin surface to assist with thermoregulation. : Unique to the axillary and perianal regions,
The common misconception is that sweat itself smells bad. In reality, sweat is mostly odorless. The distinct smell associated with the armpit is the result of a symbiotic (and sometimes smelly) relationship between humans and bacteria. Anatomical Structure of Axillary Sweat Glands : Distributed
Why do humans have such active, odorous glands in the armpit? Evolutionary biologists suggest that axillary secretions function as (chemical signals).
