where are the sweat glands located on the head?
the cranium
the number of active sweat glands varies greatly among different people, though comparisons between different areas (ex. axillae vs. groin) show the same directional changes (certain areas always have more active sweat glands while others always have fewer). according to henry gray's estimates, the palm has around 370 sweat glands per cm; the back of the hand has 200 per cm; the forehead has 175 per cm; the breast, abdomen, and forearm have 155 per cm; and the back and legs have 60–80 per cm.

in humans, the formation of body odors is caused by factors such as diet, gender, health, and medication, but the major contribution comes from bacterial activity on skin gland secretions. humans have three types of sweat glands; eccrine sweat glands, apocrine sweat glands and sebaceous glands. eccrine sweat glands are present from birth, while the two latter become activated during puberty. among the different types of human skin glands, the body odor is primarily the result of the apocrine sweat glands, which secrete the majority of chemical compounds needed for the skin flora to metabolize it into odorant substances. this happens mostly in the axillary (armpit) region, although the gland can also be found in the areola, anogenital region, and around the navel. in humans, the armpit regions seem more important than the genital region for body odor which may be related to human bipedalism. the genital and armpit regions also contain springy hairs which help diffuse body odors.
