MICROANATOMY

Detailed explanation-1: -The sympathetic nervous system is the component of the ANS that is responsible for controlling the human body’s reaction to situations of stress or emergency (otherwise known as the “fight-or-flight” response), while the parasympathetic nervous system is generally responsible for basal organ system function.

Detailed explanation-2: -What does the peripheral nervous system do? The nerves of the peripheral nervous system are responsible for relaying information between the body and the brain. This includes involuntary body functions such as breathing, blood flow, and heartbeat as well as sensory information and control of voluntary movement.
