FAQs on Short Tricks: Neural Control & Coordination Video Lecture - Biology Class 11 - NEET

1. What is the role of neurons in neural control and coordination?
Ans. Neurons are the fundamental units of the nervous system responsible for transmitting signals throughout the body. They play a crucial role in neural control and coordination by receiving, processing, and sending information between the brain and other body parts, enabling appropriate responses to stimuli.
2. How do reflex actions demonstrate neural coordination?
Ans. Reflex actions are involuntary responses to stimuli that occur through a reflex arc, which includes sensory neurons, interneurons, and motor neurons. This pathway allows for rapid responses without conscious thought, demonstrating how neural coordination can facilitate quick reactions to protect the body from harm.
3. What are the main components of the central nervous system?
Ans. The central nervous system (CNS) consists of the brain and spinal cord. The brain processes sensory information, regulates bodily functions, and coordinates voluntary movements, while the spinal cord serves as a communication pathway between the brain and the peripheral nervous system.
4. How do neurotransmitters influence neural communication?
Ans. Neurotransmitters are chemical messengers released by neurons that transmit signals across synapses to other neurons, muscles, or glands. They influence neural communication by binding to specific receptors, leading to excitation or inhibition of the receiving neuron, thus playing a vital role in regulating various bodily functions.
5. What is the difference between the somatic and autonomic nervous systems?
Ans. The somatic nervous system controls voluntary movements by innervating skeletal muscles, allowing conscious control over actions. In contrast, the autonomic nervous system regulates involuntary functions such as heart rate, digestion, and respiratory rate, operating without conscious awareness and further divided into sympathetic and parasympathetic systems.
