What does “Nerve impulse” actually mean in Neural Control & Coordination, and why does it matter for NEET?

an electrical signal (action potential) travels within a neuron; a chemical signal crosses the synapse.

In simple words: an electrical signal (action potential) travels within a neuron; a chemical signal crosses the synapse. Getting Nerve impulse clear matters because NEET questions on Neural Control & Coordination usually test this idea directly, not just a formula you memorised.

Key point

Nerve impulse

Common mistake

thinking the impulse jumps the synapse as electricity.

Memory tip

within a neuron = electrical; across a synapse = chemical (neurotransmitter).
