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

1. What is the function of the nervous system?

Ans. The primary function of the nervous system is to control and coordinate the activities of different parts of the body. It receives information from the sensory organs, processes it, and sends appropriate signals to the muscles and glands, allowing the body to respond to stimuli.

2. How does the nervous system coordinate body movements?

Ans. The nervous system coordinates body movements through a complex network of neurons. When a stimulus is detected, sensory neurons transmit the signal to the brain. The brain interprets the information and sends appropriate instructions to motor neurons, which then stimulate the muscles to contract or relax, resulting in coordinated body movements.

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 consists of the brain and spinal cord, while the PNS includes all the nerves that connect the CNS to the rest of the body.

4. How does the nervous system control involuntary actions?

Ans. The nervous system controls involuntary actions through the autonomic nervous system (ANS). The ANS regulates functions such as heart rate, digestion, and breathing, which occur automatically without conscious effort. It consists of two branches: the sympathetic nervous system, which prepares the body for action, and the parasympathetic nervous system, which promotes relaxation and normal bodily functions.

5. What happens when the nervous system is damaged or impaired?

Ans. When the nervous system is damaged or impaired, it can lead to various neurological disorders. These disorders can affect different aspects of control and coordination, such as movement disorders like Parkinson's disease, sensory disorders like peripheral neuropathy, or cognitive disorders like Alzheimer's disease. Treatment options for these conditions depend on the specific disorder and may include medication, therapy, or surgery.
