Answer;
Parasympathetic nervous system	Sympathetic nervous system
Introduction	The 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.
Function	Control the body's response while at rest.	Control the body's response during perceived threat.
Originates in	Sacral region of spinal cord, medulla, cranial nerves 3, 7, 9, and 10	Thoracic and lumbar regions of spinal cord
Activates response of	Rest and digest	Fight-or-flight
Neuron Pathways	Longer pathways, slower system	Very short neurons, faster system
General Body Response	Counterbalance; restores body to state of calm.	Body speeds up, tenses up, becomes more alert. Functions not critical to survival shut down.
Cardiovascular System (heart rate)	Decreases heart rate	Increases contraction, heart rate
Pulmonary System (lungs)	Bronchial tubes constrict	Bronchial tubes dilate
Musculoskeletal System	Muscles relax	Muscles contract
Pupils	Constrict	Dilate
Gastrointestinal System	Increases stomach movement and secretions	Decreases stomach movement and secretions
Salivary Glands	Saliva production increases	Saliva production decreases
Adrenal Gland	No involvement	Releases adrenaline
Glycogen to Glucose Conversion	No involvement	Increases; converts glycogen to glucose for muscle energy
Urinary Response	Increase in urinary output	Decrease in urinary output
Neurotransmitters	neurons are cholinergic: acetylcholine	neurons are mostly adrenergic: epinephrine / norepinephrine (acetylcholine)
