Other than sweating are there other sympathetic cholinergic neuron functions?

In addition sweating, sympathetic cholinergic neurons have other important functions in the body. These functions include:

- Salivary gland secretion: Sympathetic cholinergic neurons stimulate the salivary glands to produce saliva. This helps to keep the mouth moist and aids in digestion.

- Lacrimal gland secretion: Sympathetic cholinergic neurons also stimulate the lacrimal glands to produce tears. This helps to keep the eyes moist and protected.

- Vasodilation in skeletal muscle: Sympathetic cholinergic neurons cause vasodilation (widening of blood vessels) in skeletal muscle. This increases blood flow to the muscles and provides them with more oxygen and nutrients.

- Piloerection: Sympathetic cholinergic neurons cause piloerection (the erection of hair follicles), which is commonly known as "goosebumps". This is a reflex response to cold temperatures or fear, and it helps to trap a layer of warm air next to the skin to conserve body heat.

Overall, sympathetic cholinergic neurons play a crucial role in maintaining homeostasis and regulating various bodily functions.
