The two methods for terminating the transmission across a synapse have to be explained. Concept Introduction: Neurotransmitters: Neurotransmitters are chemicals that transmit messages from the nervous system to the target cell. They are the chemical messagers where the electrical signal from the nervous system is travelled from one neuron to another to reach the target cell. Presynaptic neurons produces neurotransmitters which are stored in the small pockets of presynaptic neurons called vesicles from where the neurotransmitters are released according to the need. After neurotransmitter completes its job, it is immediately removed from the cleft of synapse for preparing the presynaptic neurons to get another impulse.

When an impulse arrives at the synapse, the synaptic vesicles open and release neurotransmitters into the cleft within a thousandth of a second. Within another ten thousandth of a second, these molecules have diffused across the cleft and bound to receptor sites in the effector cell. In what two ways is transmission across a synapse terminated so that the neuron’s signal is concluded?

Let’s say the synapses of a neuron’s dendrites are filled with glutamate-gated channels which, when activated by glutamate, cause an excitatory postsynaptic potential (EPSP) in the neuron. In one instance, glutamate is released at all of the synapses simultaneously and this leads to an action potential in the neuron. A) What type of summation of PSPs is this? Why? B) List the sequence of steps that occur starting from binding of glutamate to the glutamate-gated channels at the synapses and ending with the membrane potential at the axon hillock returning to resting potential at the end of the action potential. (Include all the changes in voltage-gated channels underlying the action potential.)

Besides the standard post- and pre-synapse that exchange information, non neuronal cell types also play a role in synaptic transmission. One of those are called astrocytes and can form a tripartite synapse. Explain the roles of astrocytes in synaptic transmission.
