FAQs on Nervous System - 2 Class 5 Worksheet Science

1. What is the main function of the nervous system in our body?
Ans. The main function of the nervous system is to control and coordinate all the activities of the body. It helps us respond to stimuli, process information, and communicate between different parts of the body through signals.
2. What are the two main parts of the nervous system?
Ans. The two main parts of the nervous system are the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord, while the PNS consists of all the nerves that connect the CNS to the rest of the body.
3. How does the brain communicate with the rest of the body?
Ans. The brain communicates with the rest of the body through a network of nerves. It sends and receives signals via these nerves, which carry messages to and from different organs and muscles, allowing for coordination of movements and responses.
4. What are neurons and why are they important?
Ans. Neurons are the basic building blocks of the nervous system. They are specialized cells that transmit information throughout the body. Neurons are important because they facilitate communication between the brain and other parts of the body, enabling us to react to our environment.
5. What role do reflex actions play in the nervous system?
Ans. Reflex actions are automatic responses to stimuli that help protect the body from harm. They occur quickly without involving the brain, allowing us to react to dangerous situations, like pulling our hand away from a hot surface, almost instantly. This quick response is crucial for safety.
