Nervous tissue provides control of other organs and sends messages through-
out your body. When you touch the rough bark on a pine tree, the branched
parts of the neuron pass the message along to allow you to process the feeling
of the tree bark.
Which of the following is the branched section of the neuron that receives the
signal from the stimulus?
