Where does the signal to release sweat come from?
Sweating is regulated by the autonomic, or sympathetic, nervous system. Signals, using the neurotransmitter acetylcholine, are sent to the sweat glands. The sweat is then released to the skin surface through ducts.Click to see full answer.

Sweating is regulated by the autonomic, or sympathetic, nervous system. Signals, using the neurotransmitter acetylcholine, are sent to the sweat glands. The sweat is then released to the skin surface through ducts.Click to see full answer. Keeping this in consideration, what do we excrete in the process of sweating?The eccrine sweat glands are distributed over much of the body. In humans, sweating is primarily a means of thermoregulation, which is achieved by the water-rich secretion of the eccrine glands. Evaporation of sweat from the skin surface has a cooling effect due to evaporative cooling.Subsequently, question is, where does sweat come from in the body? Sweat, or perspiration, is a liquid made by the skin when the body is hot. Sweat is made in sweat glands under the surface of the skin. It comes out of tiny holes in the skin called pores. Sweat is mostly water, but it also contains some salts. In this manner, what stimulates sweat glands? 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 gland’s muscarinic receptors.Why does sweat evaporate?Sweat helps cool you down by releasing moisture onto your skin. But that’s not all that’s going on. On a hot day, your sweat evaporates from your skin taking a little bit of your body heat with it. So your sweat won’t evaporate very much because the humid air can’t hold very many more water molecules.
