Question 5 (Mandatory) (1 point) Which of the following statements regarding the transmission of nerve impulses is incorrect? 0 A stimulus initiates the opening of Na* channels at the axon plasma membrane. The cell depolarizes from a resting potential of -70 mV to +40 mV, which initiates the opening of voltage gated K+ channels. The nerve impulse can travel in both directions along the neuron axon. The neuron quickly returns to its resting potential of-70 mV. At the synapse, the nerve impulse triggers the release of synaptic vesicles

Explanation / Answer

The nerve impulse can travel in both directions along the neuron axon - this is wrong statement.

Neurons are specialised for unidirectional conduction of impulse. Dendrites recieves the signal and axon transmit the signal to next neuron, no reverse flow can occur.
