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.
What is nervous system and its function?
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 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.
What are the 3 nervous systems?
The nervous system comprises the central nervous system, consisting of the brain and spinal cord, and the peripheral nervous system, consisting of the cranial, spinal, and peripheral nerves, together with their motor and sensory endings.
What are the 4 main parts of the nervous system?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body.
Why the nervous system is important?
The nervous system plays a role in nearly every aspect of our health and well-being. It guides everyday activities such as waking up; automatic activities such as breathing; and complex processes such as thinking, reading, remembering, and feeling emotions. The nervous system controls: Brain growth and development.
Which organ is part of our 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 is nervous system English?
The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. Image Credit: VectorMine / Shutterstock.com. The nervous system includes both the Central nervous system and Peripheral nervous system.
How our nervous system works?
The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.
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.
What are the 3 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.
What are the top 3 common nervous system disorders?
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.
Which body part sends messages to the brain?
The peripheral nervous system carries messages to and from the central nervous system. It sends information to the brain and carries out orders from the brain. Messages travel through the cranial nerves, those which branch out from the brain and go to many places in the head such as the ears, eyes and face.
Which is the largest part of the brain?
Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement. Cerebellum: is located under the cerebrum.
How many types of nervous system are there?
The nervous system of vertebrates (including humans) is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The (CNS) is the major division, and consists of the brain and the spinal cord.
