Which option correctly relates a nerve impulse to the process at a synapse?
Answer and explanation
Correct answer: The message travels electrically inside a neuron and chemically across a synapse
A nerve impulse is transmitted along a neuron as an electrical change in the cell membrane. At the synapse, there is a small gap between neighbouring neurons, so neurotransmitter chemicals are released by one neuron and act on the next one. Option A correctly describes this electrical-to-chemical transfer. Food, light, blood, bone, and hormones do not represent the normal mechanism of synaptic transmission.
