|
The nerve impulse could not be transmitted because it must be initiated at the dendrite end of a neuron.
|
|
|
Since neuron transmission is one-way, the nerve impulse would only be transmitted to the end of the exon and then through neurotransmitters to the next neuron.
|
|
|
The nerve impulse would go both directions from the stimulus point, but only the axon end could transfer the message through neurotransmitters to another neuron
|
|
|
The nerve impulse would go both directions and the dendrite end would be stimulated to send a second message through this neuron.

Detailed explanation-1: -What happens if a neuron is stimulated enough midway in an axon to trigger an action potential? The nerve impulse would go both directions from the stimulus point, but only the axon end could transfer the message trough neurotransmitters to another neuron.
Detailed explanation-2: -When a neuron is sufficiently stimulated to reach the neural threshold (a level of stimulation below which the cell does not fire), depolarization, or a change in cell potential, occurs. Potentials. The term potential refers to a difference in electrical charges.
Detailed explanation-3: -If a stimulus is strong enough, an action potential occurs and a neuron sends information down an axon away from the cell body and toward the synapse. Changes in cell polarization result in the signal being propagated down the length of the axon. The action potential is always a full response.
Detailed explanation-4: -A nerve impulse begins when a neuron receives a chemical stimulus. The nerve impulse travels down the axon membrane as an electrical action potential to the axon terminal. The axon terminal releases neurotransmitters that ca rry the nerve impulse to the next cell.
