4. The membrane of the neuron sending the signal
10. The branch of the nervous system responsible for the "fight-or-flight" response. (
11. Molecules released by neurons to transmit signals across a synapse
13. The part of the neuron that carries signals away from the cell body
14. The gap between two neurons where neurotransmitters travel.
16. The membrane of the neuron receiving the signal
18. The process by which neurotransmitters are taken back into the presynaptic neuron.
19. Neurotransmitter associated with attention, alertness and arousal
20. The neurotransmitter involved in learning, memory and muscle movement
