  • Which of the following statements about transmission of nerve impulse is incorrect? (a) Nerve impulse travels from dendritic end towards axonal end

Which of the following statements about the transmission of nerve impulses is incorrect?

(a) Nerve impulse travels from the dendritic end towards the 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

Answers (1)

Explanation: Sensory neurons carry the nerve impulses generated at the sensory receptor towards the CNS. The nerve impulse is transmitted through the axon of one neuron to the dendrite of another neuron. At the end of the axon, neurotransmitters are released which flow through the synapse to the dendrite of another neuron. Hence, (c) is the correct option.
