How is nervous system classified?
The nervous system is classified into the central and peripheral nervous system. The central nervous system (CNS) consists of the brain and spinal cord, leaving everything else in the peripheral nervous system (PNS).
Can stress cause nervous system problems?
Early life stress can change the development of the nervous system as well as how the body reacts to stress. These changes can increase the risk for later gut diseases or dysfunctioning.
What is nervous system Class 5?
The nervous system is a system in the body which sends signals around the body. It lets people and animals respond to what is around them. The structure of the system includes the brain and spinal cord, which together are called the central nervous system.

- The sympathetic nervous system.
- The parasympathetic nervous system.

What is the treatment of nervous system?
Treatment of nervous system-related diseases or disorders may also include: Medicines, possibly given by a drug pumps (such as those used for people with severe muscle spasms) Deep brain stimulation. Spinal cord stimulation.
What diseases affect the nervous system?
Brain and nervous system problems are common. These neurological disorders include multiple sclerosis, Alzheimer’s disease, Parkinson’s disease, epilepsy, and stroke, and can affect memory and ability to perform daily activities.
What are the common signs of stress?

What is the role and function of the nervous system?
The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).
What are the three functions of the central nervous system?
The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output.
What attacks the nervous system?
What is Guillain-Barré syndrome? Guillain-Barré syndrome (GBS) is a rare neurological disorder in which the body’s immune system mistakenly attacks part of its peripheral nervous system—the network of nerves located outside of the brain and spinal cord.
Why is the nervous system important?
The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.
What is the nervous system simple definition?
The nervous system controls everything you do, including breathing, walking, thinking, and feeling. This system is made up of your brain, spinal cord, and all the nerves of your body. The nerves carry the messages to and from the body, so the brain can interpret them and take action.
What is the main function of the nervous system?
The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory.
What are the two main components of the nervous system?
The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
What are the characteristics of the nervous system?
Characteristics Of Nervous Tissue
- Nervous tissue makes up for the CNS and PNS of the nervous system.
- Contains two distinct cells – neurons and glial cells.
- It consists of the dendrites, cell body, axon and nerve endings.
What are the 3 main divisions of the nervous system?
The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else (Figure 8.2).
What is nervous system short answer?
The nervous system is a body system which sends signals around the body. It lets animals respond to what is around them. The central nervous system is the brain, the spinal cord, and nerves. It is present in almost all animals. It is there to process the input from the senses, and to to coordinate movement.
Can you live without the nervous system?
Without the nervous system our brain would be mush. It wouldn’t know anything that was going on in the outside world and wouldn’t be able to control our body. The brain and the spinal cord make up what is called the central nervous system. The rest of the nerves together are called the peripheral nervous system.
What is unique about the nervous system?
The nervous system is the body’s inner communication system. It’s made up of the body’s many nerve cells. The nerve cells take in information through the body’s senses: touch, taste, smell, sight, and sound. The brain interprets these sensory cues to understand what’s going on outside and inside the body.
What is nervous system in human body?
The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.
