| Front | What is an Axon? |
| Back | An extension of the cytoplasm, which transmits impulses away from the cell body to axon endings. |
| Front | Define and give an example of Receptors |
| Back | Sends an electrical impulse in response to a stimulus to the CNS along neurones(Photo/thermo/osmo/mechano/chemo)receptors |
| Front | What happens during the refractory period? |
| Back | The charge is lower than the resting potential (< -70mV).[Na+] / [K+] restored.Another impulse cannot be sent during the refractory period, ensuring unidirectional transmission transport. |
