ANATOMY

Detailed explanation-1: -The molecules of neurotransmitter diffuse across the synaptic cleft and bind to receptor proteins on the postsynaptic cell.

Detailed explanation-2: -The surface of the dendrites is filled with receptors that become enacted upon by neurotransmitters that traversed the synapse after the pre-synaptic neuron fired and released neurotransmitters into the synapse.

Detailed explanation-3: -Neurons talk to each other across synapses. When an action potential reaches the presynaptic terminal, it causes neurotransmitter to be released from the neuron into the synaptic cleft, a 20–40nm gap between the presynaptic axon terminal and the postsynaptic dendrite (often a spine).

Detailed explanation-4: -Myelin Sheath covers the axon to protect it and help messages travel faster and easier. Dendrites receive messages from other neurons. Axon sends messages from the cell body to the dendrites of other neurons.
