FAQs on Neural Control and Coordination Practice Questions - DPP for NEET

1. What is neural control and coordination?
Ans. Neural control and coordination is the process by which the nervous system regulates and coordinates the activities of different organs and systems in the body. It involves the transmission of electrical signals, called nerve impulses, between neurons, enabling communication and control throughout the body.
2. How does the nervous system coordinate body movements?
Ans. The nervous system coordinates body movements through a combination of sensory input, integration of information in the central nervous system, and motor output. When a stimulus is detected by sensory receptors, nerve impulses are transmitted to the brain or spinal cord for processing. The brain then sends motor signals to the appropriate muscles, causing them to contract or relax and produce the desired movement.
3. What are the major components of the nervous system?
Ans. The nervous system consists of two main components: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord, which are responsible for processing and integrating information. The PNS consists of nerves that connect the CNS to the rest of the body, allowing for communication and control.
4. How does the nervous system regulate bodily functions?
Ans. The nervous system regulates bodily functions through a combination of the autonomic and somatic nervous systems. The autonomic nervous system controls involuntary functions such as heart rate, digestion, and respiration. It consists of the sympathetic and parasympathetic divisions, which have opposing effects on these functions. The somatic nervous system controls voluntary movements and sensory perception.
5. What are the common disorders associated with neural control and coordination?
Ans. There are several disorders associated with neural control and coordination, including Parkinson's disease, Alzheimer's disease, multiple sclerosis, and stroke. Parkinson's disease affects movement and is characterized by tremors, rigidity, and difficulty with coordination. Alzheimer's disease affects memory, thinking, and behavior. Multiple sclerosis is an autoimmune disease that affects the communication between nerve cells. Stroke occurs when the blood supply to the brain is interrupted, leading to neurological deficits.
