AP PSYCHOLOGY

Detailed explanation-1: -Two mechanisms have evolved to transmit nerve signals. First, within cells, electrical signals are conveyed along the cell membrane. Second, for communication between cells, the electrical signals generally are converted into chemical signals conveyed by small messenger molecules called neurotransmitters.

Detailed explanation-2: -Transmission of a signal between neurons is generally carried by a chemical called a neurotransmitter. Transmission of a signal within a neuron (from dendrite to axon terminal) is carried by a brief reversal of the resting membrane potential called an action potential.

Detailed explanation-3: -Now that we’ve reviewed the anatomy of a neuron and how this anatomy helps to transmit the electrical impulse to the next neuron, we can answer the question. The correct outline for the sequence of transmission of an electrical impulse through a neuron is dendrites, cell body, axon, axon terminal.
