Neurons are cells within the nervous system which transmit messages to other nerves cells, gland cells, muscles cells, etc. Neurons have specialized projections called axon and dendrites. Dendrites take information to the cell body while axon takes information away from the cell body. Synapses are the contact points where the neurons communicate with one another. The dendrites are covered with synapses formed by the ends of the axons from other neurons. At the synaptic terminal, an electrical impulse will trigger the migration of vesicles containing neurotransmitters towards the pre-synaptic membrane. The vesicle membrane will then fuse with the pre-synaptic membrane releasing the neurotransmitters into the synaptic cleft.
