Rearrange the following in the correct order of involvement in electrical impulse movement:
$(i)$ Synaptic knob
$(ii)$ Dendrites
$(iii)$ Cell body
$(iv)$ Axon terminal
$(v)$ Axon

(A) The electrical impulse travels through a neuron in the following sequence:
$1$. Dendrites $(ii)$: These receive the signal.
$2$. Cell body $(iii)$: The signal is processed here.
$3$. Axon $(v)$: The impulse travels along the axon.
$4$. Axon terminal $(iv)$: The signal reaches the end of the axon.
$5$. Synaptic knob $(i)$: The signal reaches the terminal bulb to trigger neurotransmitter release.
Therefore,the correct order is $(ii) \rightarrow (iii) \rightarrow (v) \rightarrow (iv) \rightarrow (i)$.
