FAQs on Neural System & Coordination Video Lecture - Biology Class 11 - NEET

1. What is the human neural system?
Ans. The human neural system refers to the complex network of nerves and cells that transmit and coordinate signals throughout the body. It includes the brain, spinal cord, and peripheral nerves, which work together to control and regulate bodily functions.
2. How does the human neural system coordinate the body?
Ans. The human neural system coordinates the body by transmitting electrical signals called nerve impulses. These impulses travel along the neurons, which are the basic building blocks of the neural system. The brain processes these signals and sends out appropriate responses to different parts of the body, allowing for coordinated movement, sensory perception, and other physiological functions.
3. What role does the spinal cord play in the human neural system?
Ans. The spinal cord is a crucial component of the human neural system. It serves as a pathway for communication between the brain and the peripheral nervous system. The spinal cord also plays a vital role in reflex actions, allowing for quick responses to certain stimuli without the need for conscious thought or decision-making.
4. How does the human neural system regulate body temperature?
Ans. The human neural system regulates body temperature through a process called thermoregulation. Specialized receptors in the skin and internal organs detect changes in temperature and send signals to the brain. The brain then activates mechanisms to either increase or decrease body temperature, such as shivering to generate heat or sweating to cool down.
5. Can the human neural system be affected by diseases or disorders?
Ans. Yes, the human neural system can be affected by various diseases and disorders. Examples include Alzheimer's disease, Parkinson's disease, multiple sclerosis, and stroke. These conditions can disrupt the normal functioning of the neural system, leading to cognitive, motor, or sensory impairments. Treatment options vary depending on the specific condition but may involve medications, therapy, or surgical interventions.
