Answer :
The parasympathetic nervous system has been activated to calm her down in a situation when she was startled awake in the middle of the night, it turned out that the noise she heard was the closet rod breaking from the weight of her winter coat.
A network of neurons called the parasympathetic nervous system helps your body to calm down after times of stress or danger. During times when you feel secure and at ease, it also aids in the operation of life-sustaining functions like digestion.
The activation of "rest-and-digest" or "feed-and-breed" processes, such as sexual desire, salivation, lacrimation (tears), urine, and digestion, takes place when the body is at rest, particularly after eating. Its actions are said to be complementary to those of the sympathetic nervous system, which is in charge of inducing the physiological processes involved in the fight-or-flight response.
