The Body and the Brain neurons first
... Each neuron is made up of a cell body, a dendrite, and an axon. The cell body looks like the top of the trunk. The cell body produces energy that fuels the activity of the cell. The axons look like the root of a tree. They carry messages away from the center cell body. The dendrites look like the br ...
