Solution

The correct option is D
Electric impulse will be hampered.

Synaptic vesicles are tiny sac-like structures containing chemicals called neurotransmitters. These neurotransmitters help in transfer of electric impulses from axon end/axon bulbs to succesive dendrites. Their absense leads to hampering of nerve impulse eventually.

Q. Question 21
Which of the following statements about transmission of nerve impulse is incorrect?

(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.
(c) The chemicals released from the axonal end of one neuron cross the synapse and generate a similar electrical impulse in a dendrite of another neuron.
(d) A neuron transmits electrical impulses not only to another neuron but also to muscle and gland cells.
