This part of the neuron receives chemical messages from other neurons.
What are dendrites?
100
Signals travel through a neuron in this direction. Use the terms axon and dendrite in your answer.
What is dendrite → axon?
100
Receptor used for sight.
What is a photoreceptor?
100
Any change in the environment that causes a reaction.
What is a stimulus?
100
Structure A
What is a dendrite?
200
This long structure carries electrical signals away from the cell body.
What is the axon?
200
Signals pass between two neurons from this structure to this structure.
What is axon to dendrite?
200
Receptor used for hearing.

200
Controls the body’s responses to changes within and outside the body.
What is the nervous system?
200
Structure B
What is a cell body?

500
Automatic response that occurs without conscious control.
Reflex
500
The gap between the two neurons
