FAQs on Class 5 Science - Nervous System - CBSE Worksheets - 1

1. What are the main functions of the nervous system?
Ans. The nervous system has several key functions, including the regulation of bodily functions, coordination of movement, processing sensory information, and enabling communication between different body parts. It plays a critical role in maintaining homeostasis, responding to environmental changes, and facilitating learning and memory.
2. What are the two major divisions of the nervous system?
Ans. The nervous system is primarily divided into two major divisions: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, which process information and coordinate responses. The PNS comprises all the nerves outside the CNS, connecting the brain and spinal cord to the rest of the body, including sensory and motor functions.
3. How does the nervous system communicate with the body?
Ans. The nervous system communicates with the body through a network of neurons that transmit electrical impulses and chemical signals. Neurons convey information via synapses, where neurotransmitters are released to relay signals between neurons, muscles, and glands, allowing for rapid communication and response to stimuli.
4. What are common disorders of the nervous system?
Ans. Common disorders of the nervous system include Alzheimer's disease, Parkinson's disease, multiple sclerosis, epilepsy, and stroke. These conditions can affect various functions such as memory, movement, and coordination, leading to significant impacts on daily living and overall health.
5. How can one maintain a healthy nervous system?
Ans. Maintaining a healthy nervous system can be achieved through a balanced diet rich in nutrients, regular physical exercise, adequate sleep, stress management techniques, and avoiding harmful substances like alcohol and drugs. Engaging in mental exercises, such as puzzles or learning new skills, can also support cognitive health and promote overall nervous system function.
