Question

Which sacral nerves carry parasympathetics?

1) S2 - S4
2) S1 - S3
3) S3 - S5
4) S4 - S6

Answer 1

The sacral nerves that carry parasympathetic nerves are S2 - S4.

Step-by-step explanation:

The sacral nerves that carry parasympathetic nerves are S2 - S4.

The parasympathetic nervous system is responsible for maintaining homeostasis and promoting rest and digestion. It consists of preganglionic and postganglionic fibers. Preganglionic fibers from the sacral region travel in spinal nerves.

For example, parasympathetic nerves from the sacral region innervate the bladder, rectum, and reproductive organs. These nerves help regulate functions such as emptying the bladder and controlling sexual arousal.
