Question

Electric impulse travels in a neuron from:

• A. Dendrite → axon → axonal end → cell body
• B. Dendrite → cell body → axon → axonal end
• C. Axonal end → axon → cell body → dendrite
• D. Cell body → dendrite → axon → axonal end

Answer 1

The correct option is B Dendrite → cell body → axon → axonal end

$\bullet$ Nerve impulse is a signal which travels along the length of the neuron. These are the means through which the information is transmitted along the neuron.
$\bullet$ The information that is received by the dendrites of a neuron initiates a chemical reaction. This creates an electrical impulse.
$\bullet$ This impulse travels from the dendrite to the cell body and then along the axon to the end ( DENDRITE→ CELL BODY→ AXON→ AXON TERMINAL)
$\bullet$ Chemicals called neurotransmitters are released at the end of the axon.
$\bullet$ These chemicals cross the gap or the synapse and then start a similar electrical impulse in the dendrite of the next neuron.
