Neurotransmission

3. A nervous system which is divided into autonomic and somatic nervous systems
5. Parasympathetic nervous system is responsible for the control (contraction) of these parts of the body
10. An electrical impulse sent down the length of the axon
11. Communication within neurons
13. Receives the nerve impulses or signals from adjacent neurons
14. A part of the central nervous system
15. Make the firing of the receiving neuron more likely
16. A part of the CNS

1. A nervous system which is divided into sympathetic and parasympathetic nervous systems
2. Protects the axon from external influences
4. Make the firing of the receiving neuron less likely
6. Nervous system which prepares us for flight-or-fight response
7. Contains neurotransmitters
8. Its axons project to the spinal cord
9. It is found between sensory input and motor output
12. Where the electrical signals pass along
