Which structure contains the specific receptors for neurotransmitters?

Neurotransmitters are chemical messengers that transmit signals across the synapse between neurons. When an action potential reaches the end of a neuron, it triggers the release of neurotransmitters into the synaptic cleft, which then diffuse across the cleft and bind to specific receptors on the post-synaptic membrane of the next neuron. The binding of neurotransmitters to their receptors on the post-synaptic membrane can either excite or inhibit the firing of the post-synaptic neuron, depending on the type of neurotransmitter and the type of receptor it binds to.

The pre-synaptic membrane is the membrane of the neuron that releases neurotransmitters into the synaptic cleft, while the synaptic vesicle is a small sac within the pre-synaptic neuron that contains the neurotransmitter molecules. The synaptic cleft is the small gap between the pre-synaptic and post-synaptic membranes where neurotransmitters are released and diffuse across.
