Question

Describe how neurons transmit information?

Answer 1

Neurons transmit information with the help of its dendrites, axon, soma and terminal buttons by converting stimuli into electrical impulses. This is done by the following method:

\[\ce{\underset{\text{Transmission of neural impulse}}{Dendrites -> Soma -> Axon -> Terminal buttons}}\]

• Dendrites receive the incoming neural impulses, from adjacent neurons or directly from the sense organs, in electrochemical form.

• The nerve impulse is then passed on to the soma that is the main body of the neuron.

• From soma, the impulse passes on to the axon.

• The axon transmits the information/impulse along its length to terminal buttons.

• The terminal buttons transmit the information to another neuron, gland, and muscle.
