Across
- 4. chemical messengers that pass on information across the synapse from neuron to neuron if a certain threshold of excitation is reached
- 6. increases the speed of electrical transmissions via saltatory conduction
- 7. tree-like structures that receive and transmit information
- 8. gap between two neurons
- 9. the system where motor neurons are located
Down
- 1. the reversal (depolarisation) & restoration (repolarisation) of the electrical potential across a plasma membrane as a nerve impulse passes along a neuron
- 2. organelle containing genetic material
- 3. conduct electrical signals down the cell body
- 5. cell body of a neuron
- 6. motor neurons control this function
