Question

I am a way of coding information, in a similar way to FM radio, allowing information to be transmitted both quickly and accurately by electrical means. Who am I?

• A. Nerve code
• B. Reflex arc
• C. Nerve impulse
• D. Brain signal

Answer 1

The correct option is C

Nerve impulse

Nerve impulses are a way of coding information, in a similar way to FM radio, allowing information to be transmitted both quickly and accurately. Nerve impulses are transmitted through a change in the concentration of sodium ions on the surface of the nerve cell which happens on receiving a stimulus by receptors and thereby by the dendrites of neurons.
