Answer to Question 1

The dendrite is the end of the neuron that receives information and it resembles a tress with many branches. It allows one neuron to receive input from thousands of other neurons. The axon is a tube-like structure that emerges from the cell body and transmits information to other neurons. The terminal buttons are the small knobs at the end of the axon that release neurotransmitters. Neurotransmitters are the chemicals released by the terminal buttons that allow neurons to communicate with each other. Myelin is a fatty sheath that wraps around neurons and enables them to transmit information more rapidly. The cell body is the center of the neuron that keeps the neuron alive.
