Have you ever heard the terms parasympathetic and sympathetic thrown around in conversations about the nervous system? While they may sound like complex medical jargon, they are actually quite simple concepts that play a crucial role in regulating our bodily functions.
The proper word is actually both – parasympathetic and sympathetic are two branches of the autonomic nervous system that work in opposition to each other to maintain homeostasis in the body. The parasympathetic nervous system is responsible for rest and digestion, while the sympathetic nervous system is responsible for the fight or flight response.
The parasympathetic nervous system is often referred to as the “rest and digest” system because it promotes activities that occur when the body is at rest, such as digestion, urination, and defecation. It works to conserve energy and slow down the heart rate, allowing the body to rest and recover.
On the other hand, the sympathetic nervous system is often referred to as the “fight or flight” system because it prepares the body for action in response to a threat. It increases heart rate, dilates the pupils, and redirects blood flow to the muscles, preparing the body to either fight or flee.
Understanding the difference between parasympathetic and sympathetic is essential in understanding how our bodies respond to stress and how we can regulate our bodily functions to achieve optimal health. In this article, we will explore the functions of each system in more detail and how they interact with each other.
Parasympathetic
The parasympathetic nervous system is a division of the autonomic nervous system that is responsible for the body’s “rest and digest” functions. It is the opposite of the sympathetic nervous system, which is responsible for the body’s “fight or flight” response. The parasympathetic nervous system is activated during times of relaxation and rest, and helps to conserve energy and promote digestion and other bodily functions.
Sympathetic
The sympathetic nervous system is a division of the autonomic nervous system that is responsible for the body’s “fight or flight” response. It is the opposite of the parasympathetic nervous system, which is responsible for the body’s “rest and digest” functions. The sympathetic nervous system is activated during times of stress, danger, or physical exertion, and helps to prepare the body for action by increasing heart rate, blood pressure, and respiration, among other things.
How To Properly Use The Words In A Sentence
Using the correct terminology in a sentence is crucial to conveying the intended meaning. In the context of the nervous system, the terms parasympathetic and sympathetic are often used interchangeably, but they have distinct meanings. Here’s how to use them properly in a sentence:
How To Use Parasympathetic In A Sentence
The parasympathetic nervous system is responsible for regulating the body’s rest-and-digest response. To use the term parasympathetic in a sentence, consider the following example:
- After a long day at work, I activated my parasympathetic nervous system by practicing deep breathing exercises and meditation.
In this sentence, parasympathetic is used to describe the state of rest and relaxation that the body enters into when the parasympathetic nervous system is activated.
How To Use Sympathetic In A Sentence
The sympathetic nervous system is responsible for regulating the body’s fight-or-flight response. To use the term sympathetic in a sentence, consider the following example:
- When I heard a loud noise in the middle of the night, my sympathetic nervous system kicked in and I felt my heart rate increase as my body prepared to defend itself.
In this sentence, sympathetic is used to describe the physiological response that occurs when the sympathetic nervous system is activated in response to a perceived threat.
By using these terms correctly, you can better communicate the specific functions of the parasympathetic and sympathetic nervous systems in the body.

Common Mistakes To Avoid
When it comes to understanding the parasympathetic and sympathetic nervous systems, there are several common mistakes that people make. These mistakes can lead to a misunderstanding of how these systems work and can even result in incorrect treatment or advice. In this section, we will highlight some of these common mistakes, explain why they are incorrect, and offer tips on how to avoid making them in the future.
Interchanging Parasympathetic And Sympathetic
One of the most common mistakes people make is using the terms parasympathetic and sympathetic interchangeably. While both systems are part of the autonomic nervous system and work together to regulate bodily functions, they have distinct roles and functions.
The sympathetic nervous system is responsible for the “fight or flight” response, which prepares the body for action in response to a perceived threat or danger. This can include increased heart rate, dilated pupils, and increased respiration. On the other hand, the parasympathetic nervous system is responsible for the “rest and digest” response, which helps the body conserve energy and promote relaxation. This can include decreased heart rate, constricted pupils, and increased digestion.
Interchanging these terms can lead to confusion and misunderstandings. For example, if someone is experiencing symptoms of anxiety, it would be incorrect to say that their parasympathetic nervous system is activated, as this system promotes relaxation rather than arousal. Similarly, if someone is experiencing symptoms of digestion issues, it would be incorrect to say that their sympathetic nervous system is activated, as this system promotes energy expenditure rather than conservation.
Tips To Avoid Interchanging Parasympathetic And Sympathetic
- Learn the distinct roles and functions of each system to better understand how they work together
- Use the correct terminology when discussing bodily functions and responses
- Double-check your understanding of these terms before providing advice or treatment to others
Context Matters
When it comes to the parasympathetic and sympathetic nervous systems, context is key. The choice between these two systems depends on the situation at hand, and what response is needed from the body. Understanding the different contexts in which these systems might be used can help to shed light on why one might be favored over the other.
Examples Of Different Contexts
One context in which the parasympathetic nervous system might be favored is during rest and digestion. This system is responsible for slowing down the body’s processes and conserving energy. When we are in a relaxed state, such as after a meal, the parasympathetic system helps to stimulate digestion and absorption of nutrients.
On the other hand, the sympathetic nervous system is often called upon during times of stress or danger. This system triggers the body’s “fight or flight” response, preparing us to respond to a perceived threat. For example, if we are walking down a dark alley and hear footsteps behind us, the sympathetic system will kick in to increase heart rate, dilate pupils, and release adrenaline to give us the energy we need to either fight or flee.
There are also situations where both systems might be activated simultaneously, such as during exercise. In this case, the sympathetic system helps to increase heart rate and blood flow to the muscles, while the parasympathetic system helps to regulate breathing and maintain a steady heart rate.
Overall, the choice between parasympathetic and sympathetic depends on the specific context and what response is needed from the body. While the sympathetic system is often associated with stress and danger, it is important to remember that both systems play important roles in maintaining bodily functions and responding to different situations.
Exceptions To The Rules
While the parasympathetic and sympathetic nervous systems generally have opposite effects on the body, there are some exceptions where their rules may not apply. Here are a few examples:
1. Adrenaline Rush
In situations of extreme stress or danger, the body releases a surge of adrenaline, which activates the sympathetic nervous system. This results in the “fight or flight” response, where the body prepares to either fight off the threat or run away from it. However, in some cases, the parasympathetic nervous system may also be activated in response to the adrenaline rush. This can lead to symptoms such as sweating, nausea, and dizziness, which are typically associated with the parasympathetic nervous system.
2. Digestive System
While the parasympathetic nervous system is primarily responsible for regulating the digestive system, the sympathetic nervous system can also have an effect on it. For example, when the body is under stress, the sympathetic nervous system may slow down or shut down digestion in order to conserve energy for other functions. This can lead to symptoms such as constipation, bloating, and nausea.
3. Bladder Control
The parasympathetic nervous system is responsible for controlling the bladder and promoting urination. However, in some cases, the sympathetic nervous system may also play a role in bladder control. For example, when the body is under stress, the sympathetic nervous system may cause the bladder to contract, leading to the urge to urinate even if the bladder is not full.
4. Sexual Function
Both the parasympathetic and sympathetic nervous systems play a role in sexual function. While the parasympathetic nervous system is responsible for promoting sexual arousal and orgasm, the sympathetic nervous system can also have an effect on sexual function. For example, when the body is under stress, the sympathetic nervous system may cause a decrease in sexual desire or performance.
5. Pain Perception
While the sympathetic nervous system is generally associated with the body’s response to pain, the parasympathetic nervous system can also play a role in pain perception. For example, some studies have suggested that activating the parasympathetic nervous system through techniques such as deep breathing or meditation can help to reduce pain and promote relaxation.
