Some examples from this set of practice questions
1.
Q: What are the primary types of neurons in the nervous system?
Answer: A: Sensory neurons, motor neurons, and interneurons.
2.
Q: What is the main function of sensory neurons?
Answer: A: To transmit sensory information from receptors to the central nervous system (CNS).
3.
Q: What is the primary role of motor neurons?
Answer: A: To convey signals from the CNS to muscles and glands to elicit a response or action.
4.
Q: What are interneurons responsible for?
Answer: A: Connecting sensory and motor neurons within the CNS and processing information.
5.
Q: What is the basic structural unit of a neuron?
Answer: A: The neuron consists of the cell body (soma), dendrites, and an axon.
6.
Q: What is the function of dendrites?
Answer: A: To receive signals from other neurons and convey them to the cell body.
7.
Q: What is the role of the axon?
Answer: A: To transmit electrical impulses away from the cell body to other neurons or muscles.
8.
Q: What is the myelin sheath and what is its function?
Answer: A: A fatty layer that covers the axon to increase the speed of electrical signal transmission.
9.
Q: What is a synapse?
Answer: A: The junction between two neurons where communication occurs, typically involving the release of neurotransmitters.
10.
Q: How does neural transmission occur at the synapse?
Answer: A: An action potential reaches the axon terminal, causing neurotransmitters to be released into the synaptic cleft, where they bind to receptors on the postsynaptic neuron.
