Secretory glands in dermal layers of the skin that produce a hypotonic sodium chloride solution in response to high body temperature. Fluid evaporates, thus inducing cooling of skin. Glands activated by cholinergic sympathetic nerve fibres.
glands found in the deeper layer of the skin (the dermis) that produce sweat, a watery fluid that forms a means of excretion for nitrogenous waste and has a role in the control of body temperature
