Quizplus · Accepted Answer

Receptor sites are specialized proteins on the surface of dendrites, muscles, and glands that are shaped to fit with only certain neurotransmitters. This allows for specific and targeted communication between neurons and between neurons and other cells in the body. A neurotransmitter will bind to its specific receptor site like a lock and key, initiating a chemical signal that can result in an excitatory or inhibitory response in the receiving neuron or cell.
