Question

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

Options

• Nerve impulse travels from dendritic end towards axonal end

• 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

• 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

• A neuron transmits electrical impulses not only to another neuron but also to muscle and gland cells

Answer 1

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

Explanation - 

Axonal end contains vesicle filled with a chemical called "neurotransmitter" which cross the gap or synapse and generate electrical impulse at the dendrite of another neuron.
