Question

difference between synthetic and parasyenthetic nervous system

Answer 1

The parasympathetic nervous system (PNS) controls homeostasis and the body at rest and is responsible for the body's "rest and digest" function. The sympathetic nervous system(SNS) controls the body's responses to a perceived threat and is responsible for the "fight or flight" response.
Parasympathetic nervous systemSympathetic nervous systemIntroductionThe parasympathetic nervous system is one of the two main divisions of the autonomic nervous system (ANS). Its general function is to control homeostasis and the body's rest-and-digest response.The sympathetic nervous system (SNS) is one of two main divisions of the autonomic nervous system (ANS). Its general action is to mobilize the body's fight-or-flight response.FunctionControl the body's response while at rest.Control the body's response during perceived threat.Originates inSacral region of spinal cord, medulla, cranial nerves 3, 7, 9, and 10Thoracic and lumbar regions of spinal cordActivates response ofRest and digestFight-or-flightNeuron PathwaysLonger pathways, slower systemVery short neurons, faster systemGeneral Body ResponseCounterbalance; restores body to state of calm.Body speeds up, tenses up, becomes more alert.

Answer 2

Synthetic nervous system:-
1) Allow body to function under stress.
2) Fight or flight.
3) Primes body for intense skeletal muscle activity.

Parasynthetic nervous system:-
1) Maintenance functions.
2) Rest and digest.
3) Counterbalances sympathetic functions.
