How does a message pass to the next neuron at a synapse?
Answer and explanation
Correct answer: Through chemical substances
The governing concept is synaptic transmission. When a nerve impulse reaches the terminal of one neuron, it causes neurotransmitter chemicals to be released into the tiny synaptic cleft. These chemicals diffuse across the gap and bind to receptors on the next neuron, initiating a new impulse. Therefore option C is correct. Blood pressure, bone movement, and digestion do not transmit a nerve message across a synapse.
