The gap between two neurons across which a nerve impulse is transmitted (chemically) is the:
AAxon
BDendrite
CSynapse
DMyelin sheath
Answer & Solution
Correct answer: C. Synapse
1. SYNAPSE is the junction between two neurons (or between a neuron and a muscle).
2. Electrical impulse triggers release of NEUROTRANSMITTER chemicals from the axon terminal.
3. They diffuse across the synapse to bind receptors on the next dendrite → new electrical signal.
