Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In what order does an impulse travel through parts of a neuron?
A
axon, synapse, dendrite, cell body
B
dendrite, axon, cell body, synapse
C
cell body, dendrite, axon, synapse
D
dendrite, synapse, axon, cell body
Explanation: 

Detailed explanation-1: -Final answer: The electrical impulse travels in a neuron from Dendrite → cell body → axon → axonal end.

Detailed explanation-2: -Synaptic knob present at the axon terminal releases the neurotransmitters that pass through the synapse and conduct the nerve impulse to the next neuron or effector cell. The correct order of involvement of the given parts of neuron in electrical impulse is Dendrites → Cell body → Axon → Axon terminal → Synaptic Knob.
