D)neurohormones
E)resting potentials

Question

Quizplus · Accepted Answer

Neurotransmitters are the chemical messengers that are released by the presynaptic neuron and bind to receptors on the postsynaptic neuron, carrying the signal between the two neurons. Threshold values and resting potentials are related to the generation of action potentials, which are the electrical signals that travel down the axon of the presynaptic neuron, but they do not carry the signal between the two neurons directly. Neurohormones are released into the bloodstream and can affect distant parts of the body, but they are not typically involved in the communication between individual neurons.
