The correct statement regarding a chemical synapse is sodium ions enter the axon terminal to signal release of neurotransmitters i.e., option B.
<h3>What is chemical synapse?</h3>
Chemical synapses are links created by two neurons or a neuron and a non-neuronal cell (muscle cell, glandular cell, sensory cell).
The synaptic complex is the basic non-reducible unit of each chemical synapse, representing the bare minimum for efficient chemical synaptic transmission.
The correct statement regarding a chemical synapse is sodium ions enter the axon terminal to signal release of neurotransmitters.
