What is the role of sweat glands in the dermis of the skin during thermoregulation?
One of the main functions of the sweat glands is to regulate the body temperature by cooling the surface of the skin.
Sweat glands are used to regulate temperature and remove waste by secreting water , sodium salt and nitrogenous wastes ( urea ) onto to rother skin surface.
Many electrolytes of sweat are sodium and chloride.
Both eccrine and apocrine sweat glands participate in thermal ( thermoregulation ) sweating. It is directly controlled by the hypothalamus. Thermal sweating is stimulated by a combination of internal body temperature and mean skin temperature.
In eccrine sweat glands stimulation occurs via activation by acetylcholine , which binds to the glands muscarinic receptors.
