If your ________ is activated, you will feel relatively at ease. somatic nervous system sympathetic nervous system parasympathetic nervous system spinal cord

Answers

Answer:

parasympathetic nervous system

Explanation:

The parasympathetic nervous system is the one that controls involuntary functions and acts. The nerves that integrate it are born in the brain, forming part of the oculomotor, facial, glossopharyngeal and vagus cranial nerves. In the spinal cord it is found at the level of the sacral roots of S2 to S4. It is responsible for the production and restoration of body energy.

The neurotransmitter of this system in pre and postganglionic neurons is acetylcholine (endogenous neurotransmitter). The nerve centers that give rise to the parasympathetic preganglionic fibers are located both in the brain and in the sacral plexus in the spinal cord. These nerve fibers branch through the territory of some cranial nerves such as the facial nerve or vagus nerve or the pelvic nerves in the sacral plexus.

The main function of the parasympathetic nervous system is to cause or maintain a state of rest or relaxation after an effort or to perform important functions such as digestion or sexual intercourse. It acts on the stress level of the organism reducing it. Performs oppositely complementary functions with respect to the sympathetic nervous system.
