The Nervous System Essay Discussion Paper
Knowing how the divisions of the nervous system work will make it easier for you to explain the signs and symptoms present in various neurological disturbances, list all the divisions of the nervous system with the corresponding major function of each.
This solution was written by a subject matter expert. It’s designed to help students like you learn core concepts. The Nervous System Essay Discussion Paper
First of all, The Nervous system is a complex network of specialized cells, called neurons that communicate with each other through electrical and chemical signals. It is responsible for coordinating and controlling all bodily functions and responses to external and internal stimuli.
- Now talking about the divisions :
The nervous system can be broadly divided into two main divisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
- Central Nervous System (CNS)
The CNS consists of the brain and spinal cord, and it serves as the control centre
for the body. It is responsible for processing and interpreting sensory information, initiating motor responses, and regulating bodily functions. The Nervous System Essay Discussion Paper
2. Peripheral Nervous System (PNS)
The PNS consists of all the nerves that lie outside of the CNS. It is further divided into two main sub-divisions:
Here we have explained first that what is nervous system and what are its two main types , further we will analyse more sub types of PNS.
Here we are going to elucidate further sub types in the PNS ( peripheral nervous system ) .
a) Somatic Nervous System
The somatic nervous system is responsible for voluntary movement and sensory input. It controls skeletal muscles and receives sensory information from the skin, muscles, and joints.
b) Autonomic Nervous System
The autonomic nervous system controls involuntary bodily functions, such as heart rate, digestion, and breathing. It is further divided into two sub-divisions:
i) Sympathetic Nervous System
The sympathetic nervous system prepares the body for “fight or flight” response by increasing heart rate, blood pressure, and respiration rate. It is activated during stressful situations.
ii) Parasympathetic Nervous System
The parasympathetic nervous system promotes relaxation and recovery by decreasing heart rate, blood pressure, and respiration rate. It is activated during restful situations. The Nervous System Essay Discussion Paper
Now this were the further divisions of the ANS ( autonomic nervous system )
Now disturbance or dysfunction in any of these divisions of the nervous system can lead to various signs and symptoms, depending on the affected structures and functions.
- For example : a disturbance in the somatic nervous system may lead to
weakness, numbness, or tingling sensations in the affected body parts
- Where as dysfunction in autonomic nervous system may lead to problems with heart rate, blood pressure, digestion, or sweating.
At last we have recognised that what can be the sign and symptoms in the nervous system when any disturbances occurs in it.
This were the divisions of nervous system and how they work which will help us recognize the sign and symptoms present if any neurological disturbances happen. The Nervous System Essay Discussion Paper
