Question

What is the role of sweat glands in the dermis of the skin during thermoregulation?

Answer 1

One of the main functions of the sweat glands is to regulate the body temperature by cooling the surface of the skin.

Explanation:

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.
