 The Autonomic Nervous SystemThe autonomic nervous system controls specific body processes, such as circulation of blood, digestion, breathing, urination, heartbeat, etc. The autonomic nervous system is named so, because it works autonomously, i.e., without a person’s conscious effort. The primary function of the autonomic nervous system is homeostasis. Apart from maintaining the body’s internal environment, it is also involved in controlling and maintaining the following life processes:
There are two types of the autonomic nervous system:
Sympathetic Autonomic Nervous System: It is the part of the autonomic nervous system, located near the thoracic and lumbar regions in the spinal cord. Its primary function is to stimulate the body’s fight or flight response. It does this by regulating the heart rate, rate of respiration, pupillary response and more. Parasympathetic Autonomic Nervous System: It is located in between the spinal cord and the medulla. It primarily stimulates the body’s “rest and digest” and “feed and breed” responses. More to Read: Human Nervous System Read on to explore more differences between the sympathetic and parasympathetic nervous systems. Difference between Sympathetic And Parasympathetic Nervous SystemThe sympathetic nervous system prepares the body for the “fight or flight” response during any potential danger. On the other hand, the parasympathetic nervous system inhibits the body from overworking and restores the body to a calm and composed state. The sympathetic and parasympathetic nervous systems are differentiated based on how the body responds to environmental stimuli. The major differences between the sympathetic and parasympathetic nervous systems are summarised below:
ConclusionThe autonomic nervous system comprises two parts- the sympathetic and parasympathetic nervous systems. The sympathetic nervous system activates the fight or flight response during a threat or perceived danger, and the parasympathetic nervous system restores the body to a state of calm. Learn more about the sympathetic and parasympathetic nervous systems, or other related topics at BYJU’S Biology Frequently Asked QuestionsThe parasympathetic nervous system restores the body to a calm and composed state and prevents it from overworking. The sympathetic nervous system, on the other hand, prepares the body for fight and flight response. What actions are controlled by the parasympathetic nervous system? (adsbygoogle = window.adsbygoogle || []).push({});Salivation, urination, lacrimation, defecation and digestion are the important body activities stimulated by the parasympathetic nervous system. What are parasympathetic ganglia?These are the autonomic ganglia of the parasympathetic nervous system that lie near or within the organs they innervate. What are the sympathetic and parasympathetic nervous system composed of?The parasympathetic nervous system is composed of cranial and spinal nerves. The sympathetic nervous system comprises cell bodies that lie within the gray column of the spinal cord. What are the major functions of sympathetic and parasympathetic autonomic nervous system?The parasympathetic nervous system restores the body to a calm and composed state and prevents it from overworking. The sympathetic nervous system, on the other hand, prepares the body for fight and flight response.
What is the function of the sympathetic division of the autonomic nervous system?The sympathetic division of the autonomic nervous system regulates the flight-or-fight responses. This division also performs such tasks as relaxing the bladder, speeding up heart rate, and dilating eye pupils.
What are the sympathetic and parasympathetic divisions of the autonomic nervous system?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.
How the sympathetic and parasympathetic divisions of the autonomic nervous system work together?The sympathetic division initiates the fight-or-flight response and the parasympathetic initiates the rest-and-digest or feed-and-breed responses. The sympathetic and parasympathetic nervous systems are important for modulating many vital functions, including respiration and cardiac contractility.
