FAQs on Nervous System : Animation - Control & Coordination Video Lecture - Class 10

1. What is the nervous system and its role in control and coordination?
Ans. The nervous system is a complex network of specialized cells called neurons that transmit signals between different parts of the body. Its main function is to coordinate and control the activities of various organs and systems in the body, allowing them to work together harmoniously.
2. How does the nervous system carry out control and coordination?
Ans. The nervous system carries out control and coordination through a process involving three main components: sensory receptors, the central nervous system (CNS), and effectors. Sensory receptors detect external stimuli or changes in the internal environment and send signals to the CNS. The CNS, consisting of the brain and spinal cord, processes these signals and generates appropriate responses. The responses are then transmitted to effectors, such as muscles or glands, which carry out the necessary actions.
3. What are the two main divisions of the nervous system?
Ans. The nervous system is divided into two main divisions: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord, while the PNS consists of nerves that extend from the CNS to various parts of the body.
4. How does the animation depict the functioning of the nervous system?
Ans. The animation demonstrates the functioning of the nervous system by illustrating how neurons transmit electrical signals, known as nerve impulses, from one part of the body to another. It shows how sensory receptors detect stimuli, how the brain processes the information received, and how motor neurons transmit signals to effectors to produce appropriate responses.
5. Why is the nervous system essential for our survival?
Ans. The nervous system is crucial for our survival because it allows us to respond to changes in our environment, maintain homeostasis, and carry out essential functions. It helps us sense and respond to danger, control our movements, regulate bodily functions, and process information, enabling us to learn, think, and make decisions. Without the nervous system, our bodies would not be able to function properly and adapt to the ever-changing world around us.
