Describe the action potential conduction and neurotransmission process from one neuron to another, electrically (including saltatory conduction) and chemically. Next, describe how a cell fires an action potential and be sure to address which structures are involved in neurotransmission. Finally, discuss reuptake and enzymatic degradation (breakdown) in the context of the appropriate neurotransmitters. Please include peer reviewed references.

READ: They key to large-scale communication in the entire nervous system is the ability to pass nerve impulses on a small scale from one neuron to the next so that signals can be transmitted throughout the entire body. The junction between two neurons is called a synapse, and is the critical space that mediates the transfer of a signal from the presynaptic neuron (the sender) to the postsynaptic neuron (the receiver) or even an effector cell (like a gland or muscle cell.) You circled a synapse in Model 1. Synapses can be electrical or chemical. Electrical synapses transmit electrical signals via gap junctions. A channel protein connects the cytoplasm of two adjacent neurons so that ions can flow directly from one cell to another to pass on the signal. However, the most common type of synapse is a chemical synapse. These utilize chemical signals, called neurotransmitters, to transmit the signal across the synaptic cleft. This is a slower process, but allows for much greater precision…
Synthetic opioids are frequently being used for analgesia, i.e. as pain killers. While morphine or other full agonists such as fentanyl are the strongest pain killers available, partial agonists such as nalorphine or pentazocine are being used in applications requiring something intermediate in strength between morphine and basic painkillers such as aspirin. Considering a situation where both morphine and pentazocine are co-administered, select the TRUE statement(s): A. With increasing concentrations of pentazocine, the percent maximal response for morphine can be reduced to the level of pentazocine. B. The dose-response curve for morphine will shift to the right and its shape will not change (parallel rightward shift). C. The dose-response curve for morphine will shift to the left and its shape will not change (parallel leftward shift). D. The maximal efficacy of morphine alone can be exceeded. E. None of the answers here is correct. Please answer asap and type your answer and…
In the space below, briefly describe how a drug might affect the transmission of a nervous signal across the synaptic cleft from a presynaptic neuron to the post synaptic neuron. In your answer give an example of one mechanism by which this drug may affect this transmission, and explain why that mechanism leads to the drug's effect. Make sure to use the correct terms for any molecules involved in this process.
Describe the biochemical signaling steps by which activation of the NMDA receptor causes the postsynaptic cell to fire larger EPSPs.
Changes in intracellular Ca2+ is one of the main governing factors that determines the direction of plasticity (i.e., whether a synapse potentiates or depresses). Provide a general mechanism to explain how changes in intracellular Ca2+ can result in either synaptic depression or synaptic potentiation (refer to our discussion on kinases and phosphatases).

Why is it used as a model for neuroinflammation? Describe microglia: where are they found, what role do they play, why can't that role be carried out the same way it is in the rest of the body? Mitofusin2 (Mfn2) is a mitochondrial protein. What is its apparent role? Can you think of a reason why overexpression could be protective against a stress? Is it reasonable that overexpression of this gene could also cause problems (if so, how)? How did the authors arrange that Mfn2 was only upregulated in the brain and spinal cord of TMFN mice, and not in other tissues of the mice? How do they demonstrate this? Briefly describe the roles of these molecules in immunity/inflammation:IL-1βIL-6IL-10TNFα They all belong to a class of molecules; what is that class called? What evidence do the authors provide that…
