Question

What is the correct direction of flow of electrical impulses?

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The correct option is C

The correct option is C.

Explanation of the correct option:

1. To carry nerve impulses, nerve cells must be in touch with one another.
2. The following route is followed by the nerve impulse: Synapse, dendrites, dendron, cyton, axon end, axon body, and so on.
3. The electrical charge represents the nerve impulse as it travels from the axon end to the synapse.
4. Electrical impulses are converted into chemical impulses in the synaptic cleft.
5. In the dendritic terminals, this nerve impulse is changed from a chemical to an electrical impulse after leaving the synaptic cleft.
6. The impulse always travels from one dendron end of a neuron to another, from one axon to another.

Final answer:

The correct direction of flow of electrical impulses i.e.,$\mathrm{Axon}\mathrm{body}\to \mathrm{axon}\mathrm{end}\to \mathrm{synapse}\to \mathrm{dendrites}\to \mathrm{dendron}\to \mathrm{cyton}\to \mathrm{axon}\mathrm{end}.$
