A target effector, such as the heart, receives input from the sympathetic and parasympathetic systems. What is the actual difference between the sympathetic and parasympathetic divisions at the level of those connections (i.e., at the synapse)?
Why does smoking increase the risk of heart disease? Provide two reasons based on autonomic function.
Compare the primary mechanisms used by the sympathetic and parasympathetic divisions to clear or remove neurotransmitters? In other words, how do they terminate their neurotransmitter activity? How do they differ from each other?
Question #2
Barbra Streisand, age 79, has asthma. We are considering an adrenergic drug for treatment. For Ms. Streisand, what are the drug advantages and diadvantages associciated with the use of
ephedrine
isoproterenol
metaproterenol
albuterol
terbutaline
Would her age be a factor in selecting the best drug? Explain.
Question #3
Steven Seagal, age 69, has hypertension and asthma. We are considering treating him with an adrenergic blocker. What are the advantages and disadvantages for each of the drugs below to treat high blood pressure?
doxazosin
prazosin
propranolol
metoprolol
atenolol
acebutolol
What needs to be included when teaching individuals suffering from high blood pressure about the use of an adrenergic blocker?
In most instances the sympathetic and parasympathetic have opposite effects on effectors where they both innervate. Describe an example where they have cooperative effects, not the opposite.

- In the sympathetic division of the autonomic nervous system: Select one: The ratio between the number of postganglionic and preganglionic neurons is small. A single preganglionic neuron usually synapses with a single postganglionic neuron. An important functional characteristic is convergence of the preganglionic fibers. Preganglionic fibers are usually much longer than the postganglionic fibers. Activity of the neurons tends to have a more generalized and widespread effect on the body.arrow_forwardIn simple terms, explain the transmission of nerve impulse at the synapse.arrow_forwardDescribe the sympathetic vasomotor tone: its origin, the neurotransmitter and receptor responsible for the effect. What is the physiological significance of the sympathetic tone?arrow_forward
- compare and contrast the differences between the sympathetic and parasympathetic nervous systems. Use the following scenarios: Scenario 1: You are walking outside late at night and you hear something in the bushes as you approach your home. Which system will dominate and what physiological changes will occur? Scenario 2: You have just finished a big dinner and now you are relaxing in your recliner to watch the big ball game. Which system will dominate and what physiological changes will occur? Be sure to at least include what happens to heart rate, blood pressure, and digestion. You may include other physiological variables as well. "Not a homework assignment"arrow_forwardthe bacterium clostridium tetani produce a toxin called tetanospasmin, the causative agent os the disease tetanus. the toxin prevents the release of inhibitory transmitters in the CNS and so blocks the resulting IPSPs they would normally generate. what are some of the functions of inhibitory synapses? considering this what symptoms would you expect from the disease tetanus, and why? ( hint: imagine trying to stand up if all of the muscles in your lower limb contracted at the same time.)arrow_forwardWhat type of synaptic potential (if any; be sure to indicate if any modification is occurring as well) would occur if: a.) An MAO inhibitor type of antidepressant is functioning at an active dopaminergic synapse that increases the rate of sodium flowing into the cell. b.) Prozac is present at an active serotonin synapse where receptor activation increases the flow of potassium out of the cell.arrow_forward

- Which of the following statements regarding postsynaptic potentials is correct? IPSPs are the result of influx of potassium ions and EPSPs are the result of efflux of sodium ions. IPSPs are the result of efflux of potassium ions and EPSPs are the result of influx of chloride ions. IPSPs are the result of efflux of potassium ions and EPSPs are the result of influx of sodium ions. IPSPs are the result of efflux of chloride ions and EPSPs are the result of efflux of calcium ions.arrow_forwardWhy does the sympathetic division produce simultaneous effects throughout the body, in contrast to parasympathetic effects, which typically are localized to specific organs?arrow_forwardA) Explain what dual innervation means with regard to the autonomic nervous system.
