Question 1:

What is the basic structural and functional unit of the nervous system?

Explanation: The basic structural and functional unit of the nervous system is the neuron. Neurons are specialized cells that transmit information through electrical and chemical signals.

Question 2:

Which part of the neuron receives signals from other neurons or sensory receptors?

Explanation: Dendrites are the part of the neuron that receives signals from other neurons or sensory receptors. They are tree-like extensions that collect information and transmit it to the cell body.

Question 3:

What is the long, fiber-like extension of a neuron that carries nerve impulses away from the cell body?

Explanation: The axon is the long, fiber-like extension of a neuron that carries nerve impulses away from the cell body. It transmits information to other neurons or effector cells, such as muscles or glands.

Question 4:

What is the electrical signal that travels along the axon of a neuron called?

Explanation: The electrical signal that travels along the axon of a neuron is called an action potential. It is a rapid change in electrical potential that allows for the transmission of information over long distances.

Question 5:

What is the small gap between two neurons where the transmission of signals occurs?

Explanation: The small gap between two neurons where the transmission of signals occurs is called a synapse. It is the site where the axon of one neuron communicates with the dendrite or cell body of another neuron.
