Dendrite > branched structure that picks up information
Dendrites are projections of a neuron that receive signals from other neurons.
Neuron > cell that carries information through the nervous system
A neuron, or nerve cell, is an electrically excitable cell that communicates with other cells with connections called synapses.
Axon > receives information and sends it away from the cell
The function of the axon is to transmit information to different neurons, muscles, and glands.
I hope this helps to better understand :)
