Question

Which of the following statement 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.

Answer 1

The correct option is 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.

Electrical impulses bring about the release of some chemicals(Neurotransmitters) at the axonal end which generate an electric impulse at the dendritic end of another neuron.
