I want to know the answer to the following question:
What do neurotransmitters attach to?
All the background I'm provided with is that "Neurotransmitters are chemicals that are released at synapses when an action potential activates them—neurotransmitters attach themselves to receptor molecules on the membrane of the synapse's target cell, and thereby alter the electrical or chemical properties of the receptor molecules.". Is that enough to answer the question?
