The nervous system relies on electrical signals for rapid communication. How does the process of synaptic transmission convert electrical signals into chemical signals and then back into electrical signals?
a) The arrival of an action potential at the axon terminal triggers the release of neurotransmitters, which bind to receptors on the postsynaptic neuron, initiating a new action potential.
b) The electrical current from the presynaptic neuron directly stimulates the postsynaptic neuron, without the involvement of chemical messengers.
c) Neurotransmitters are released from the dendrites of the presynaptic neuron and diffuse across the synaptic cleft to bind to receptors on the axon terminal of the postsynaptic neuron.
d) The action potential is converted into a chemical signal by the release of hormones, which then bind to receptors on the postsynaptic neuron.
