Question

place a single word into each sentence to make it correct. 1. an unmyelinated axon has voltage - gated ion gates along its entire (click to select). 2. an action potential at the (click to select) zone causes sodium to diffuse into the cell. 3. this results in membrane (click to select). 4. the depolarization causes a (click to select) that excites the entire membrane. 5. this continues until the traveling signal reaches the end of the (click to select). (click to select) axon cell decline depolarization repetition repolarization trigger length

Explanation:

1. Voltage - gated ion gates are along the entire length of an unmyelinated axon.
2. Action potential at the trigger zone causes sodium influx.
3. Sodium influx leads to membrane depolarization.
4. Depolarization generates a trigger that excites the membrane.
5. The signal travels until the end of the axon.

Answer:

1. length
2. trigger
3. depolarization
4. trigger
5. axon
