Detailed explanation-1: -(a) Nerve impulse travels from dendritic end towards axonal end. (b) At the dendritic end electrical impulses bring about the release of some chemicals which generate an electrical impulse at the axonal end of another neuron.
Detailed explanation-2: -Answer and Explanation: An action potential (nerve impulse) is an electrical signal that travels down the axon of a neuron, resulting in the release of neurotransmitters into the synapse.
Detailed explanation-3: -If depolarization exceeds a certain threshold, an impulse (i.e., action potential) will travel along the neuron. Various mechanisms ensure that the action potential propagates in only one direction, toward the axon tip. The generation of an action potential is sometimes referred to as “firing.”
Detailed explanation-4: -Transmission of a signal between neurons is generally carried by a chemical called a neurotransmitter. Transmission of a signal within a neuron (from dendrite to axon terminal) is carried by a brief reversal of the resting membrane potential called an action potential.
Detailed explanation-5: -Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite. The binding allows the nerve impulse to travel through the receiving neuron.
