A patient has been exposed to the organophosphate pesticide malathion,which inactivates acetylcholinesterase. Which of the following symptoms would you predict: blurring of vision, excess tear formation, frequent or involuntary urination, pallor (pale skin), muscle twitching, orcramps? Would atropine be an effective drug to treat the symptoms?(See Clinical Impact 16.2 for the action of atropine.) Explain.
We talked about drug effects on neurons in sequence. The effect of alcohol is multi-faceted and the following question asks you to apply your knowledge. Imagine two neurons in sequence. The presynaptic neuron is GABAnergic and the postsynaptic neuron is dopaminergic.
The effects of alcohol are not fully understood but it does seem to inhibit GABAnergic neurons. How would the release of dopamine from the postsynaptic neuron change in this case? Explain your answer, being sure to make each connection between concepts clear.
If alcohol instead inhibited dopaminernergic neurons, in what way might the ion flow change in the dendrites of the postsynaptic neuron of this example?
Epinephrine binds to both β-adrenergic and α-adrenergic receptors. Describe the opposite actions on the effector protein, adenylyl cyclase, elicited by the binding of epinephrine to these two types of receptors. Describe the effect of adding an agonist or antagonist to a β-adrenergic receptor on the activity of adenylyl cyclase.
