GENERAL HISTOLOGY

Detailed explanation-1: -The two divisions of the autonomic nervous system are the sympathetic division and the parasympathetic division. The sympathetic system is associated with the fight-or-flight response, and parasympathetic activity is referred to by the epithet of rest and digest. Homeostasis is the balance between the two systems.

Detailed explanation-2: -In response to a perceived threat, the sympathetic nervous system activates the fight or flight response, while the parasympathetic nervous system restores the body to a state of calm.

Detailed explanation-3: -Your sympathetic and parasympathetic nervous systems have opposite roles. While your sympathetic nervous system carries signals that put your body’s systems on alert, your parasympathetic carries signals that relax those systems. The two systems work together to keep your body in balance.
