FAQs on Infographics: Nervous System - Science Class 10

1. What are the main components of the nervous system?
Ans. The nervous system is primarily composed of two main parts: 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 branch out from the spinal cord and extend to other parts of the body.
2. How does the nervous system communicate within the body?
Ans. The nervous system communicates through a complex network of neurons that transmit signals via electrical impulses and chemical neurotransmitters. Neurons send signals to each other at synapses, allowing for rapid and coordinated responses to stimuli.
3. What are the functions of the different types of neurons?
Ans. There are three main types of neurons: sensory neurons, motor neurons, and interneurons. Sensory neurons transmit sensory information from the body to the CNS, motor neurons carry signals from the CNS to muscles and glands, and interneurons connect neurons within the CNS, processing information and coordinating responses.
4. What role does the autonomic nervous system play?
Ans. The autonomic nervous system (ANS) regulates involuntary bodily functions, such as heart rate, digestion, and respiratory rate. It is divided into the sympathetic and parasympathetic systems, which prepare the body for "fight or flight" responses and promote "rest and digest" activities, respectively.
5. How can one maintain a healthy nervous system?
Ans. Maintaining a healthy nervous system can be achieved through a balanced diet rich in vitamins and omega-3 fatty acids, regular physical activity, adequate sleep, stress management techniques, and avoiding harmful substances like excessive alcohol and drugs. Regular health check-ups also help in early detection of potential issues.
