During Propagation of Nerve Impulse?

During the propagation of the nerve impulse, the action potential results from the movement of. ... Hint: A nerve impulse or the action potential is generated by the movement of the sodium and the potassium ions in and outside the membrane. This movement leads to the generation of the impulse in the neuron.

What is the propagation of nerve impulse?

According to the membrane theory, nerve impulse is a propagated wave of de-polarisation. ... This reversed polarity is due to increased permeability of Na⁺ to the membrane, which develops de-polarisation wave. ii) A local circuit current flows between the de-polarised membrane and the resting membrane areas.

What happens during passage of nerve impulse?

When the nerve impulse reaches an axon terminal it causes the release of a chemical ( called a neurotransmitter ) that travels across the gap (the synapse) between a terminal and the dendrite of the neighboring neuron.
