Question 1:

What is the main function of a neuron?

Explanation: The main function of a neuron is the transmission of nerve impulses, allowing communication within the nervous system.

Question 2:

Which part of a neuron receives incoming signals from other neurons?

Explanation: Dendrites are the part of a neuron that receive incoming signals from other neurons or sensory receptors.

Question 3:

Which part of a neuron carries the electrical signal away from the cell body?

Explanation: The axon is responsible for carrying the electrical signal away from the cell body and towards other neurons or target cells.

Question 4:

What is the fatty substance that insulates the axon and speeds up signal transmission called?

Explanation: The fatty substance that insulates the axon and speeds up signal transmission is called the myelin sheath.

Question 5:

What is the small gap between two neurons where chemical communication occurs?

Explanation: The small gap between two neurons where chemical communication occurs is called the synapse.
