Difference Between Sympathetic & Parasympathetic Nervous Systems
The below table lists the major differences between the Sympathetic and Parasympathetic Nervous Systems:
Characteristics |
Sympathetic Nervous System |
Parasympathetic Nervous System |
---|---|---|
Definition |
The sympathetic nervous system is a portion of the nervous system that is responsible for producing reflex cardiovascular system alterations as well as localized adjustments, such as sweating in reaction to a rise in body temperature. |
The parasympathetic nervous system is a branch of the nervous system that largely regulates visceral organs like glands. |
Function |
The main goal is to initiate a fight-or-flight response. |
The primary goal is controlling the body’s feed and breed reactions, which are then followed by the rest and digest reactions. |
Salivary Glands |
It decreases Saliva production. |
It increases the flow of saliva. |
Glucose Level |
It helps with the process of turning glycogen into glucose so that muscles can get the energy they need. |
There is no involvement of the parasympathetic nervous system. |
Urinary Response |
It assists in lowering urine production. |
It helps to boost urine production. |
Heart Rate |
Results in increase of heart rate. |
It slows the heart rate. |
Pupil |
It aids in the expansion of the pupils. |
It helps to make the pupil contract. |
Muscles |
It stresses the muscles more. |
It relaxes muscles and releases stress. |
Difference Between Sympathetic And Parasympathetic
The Sympathetic and Parasympathetic Nervous Systems are a part of the Autonomic Nervous System (ANS) present in the human body. The ANS regulates internal organ function by supplying smooth muscles and glands. One of the major subsystems of the ANS is the sympathetic nervous system (SNS), which is primarily responsible for the fight-or-flight response. Another antagonistic set of ANS is the Parasympathetic Nervous System (PSNS). It mostly regulates visceral organs.
