1. What is the main function of the nervous system?
Answer: The main function of the nervous system is to transmit signals between different parts of the body, allowing for communication and coordination of various bodily functions.
2. What are the two main divisions of the nervous system?
Answer: The two main divisions of the nervous system are the central nervous system (CNS) and the peripheral nervous system (PNS).
3. What is the role of the central nervous system?
Answer: The central nervous system consists of the brain and spinal cord and is responsible for processing and interpreting sensory information, as well as coordinating motor responses.
4. What is the role of the peripheral nervous system?
Answer: The peripheral nervous system consists of nerves that extend from the central nervous system to the rest of the body and is responsible for transmitting sensory information to the CNS and carrying motor signals from the CNS to muscles and glands.
5. What are the two main types of cells in the nervous system?
Answer: The two main types of cells in the nervous system are neurons and glial cells.
6. What is the function of neurons?
Answer: Neurons are specialized cells that transmit electrical and chemical signals throughout the body, allowing for communication between different parts of the nervous system.
7. What is the function of glial cells?
Answer: Glial cells provide support and protection for neurons, as well as help regulate the chemical environment of the nervous system.
8. What is a synapse?
Answer: A synapse is a junction between two neurons or between a neuron and a muscle or gland, where signals are transmitted through the release of neurotransmitters.
9. What is the role of neurotransmitters in the nervous system?
Answer: Neurotransmitters are chemical messengers that transmit signals between neurons at synapses, allowing for communication and coordination of various bodily functions.
10. What is the fight or flight response and how is it controlled by the nervous system?
Answer: The fight or flight response is a physiological reaction to stress or danger, characterized by an increase in heart rate, blood pressure, and adrenaline levels. It is controlled by the autonomic nervous system, specifically the sympathetic division, which activates the body's stress response.
