5 bio The picture below shows the body's response to acute stress, which is to release adrenaline(norepinephrine). If a hypertensive patient is treated with adrenergic receptor agonist, how do you think themedicine will help lower his BP?SourceAdrenal medullaShort-term stressHormoneEpinephrine, norepinephrineMajor• Increase heart rate and blood pressure• Dilate airways, so breathing rate increases• Increase metabolic rate• Slow digestionresponsesactivity of adrenaline will be blocked preventing its effect on heart rate and blood volumeO activity of adrenaline will be blocked preventing its effect on heart rate and sodium and water retentionactivity of adrenaline will be blocked preventing its effect on sodium and water retentionO activity of adrenaline will be blocked preventing its effect on heart rate and blood vessel diameter

C) Potentiation of synapses between glumate-releasing neurons and dopamine-releasing neurons in the VTA. D) Increased dendrite length and greater synaptic complexity in the nucleus accumbens and prefrontal lobes.

Which of the following statements about steroid and non-steroid hormones is false?a. Non-steroid hormones typically act through second messengers such as cAMP.b. Non-steroid hormones are not lipid soluble and cannot enter the target cell.c. Steroid hormones act usually slower than non-steroid hormones.d.

What is the most likely mechanism producing tolerance to cocaine and then the dysphoria that is associated with cocaine withdrawal? A. Dynorphin neurons cause presynaptic inhibition to decrease dopamine release into the nucleus accumbens B. Cocaine runs the dopamine transporter backwards to cause tolerance and withdrawal C. cocaine binds to opiate receptors in the ventral tegmental area (VTA) D. Dynorphin neurons stimulate dopamine neurons in the ventral tegmental area (VTA) and increase dopamine release into the nucleus accumbens
A patient takes a stimulant that produces euphoria, as well as an increase in heart rate and blood pressure and it treats narcolepsy. To exert its effect, the drug must be taken up into nerve terminals, where it stimulates the release of norepinephrine and dopamine from their vascular storage sites.

Oxycodone has a high affinity for the mu receptor, and when it binds to this receptor, it produces a much stronger analgesic response than that of the endorphins produced by the body. Which term is most appropriate for this type of action? O Agonist enzyme interaction Antagonist receptor interaction Agonist receptor interaction
Imagine that a new type of psychoactive drug has been developed in a laboratory. It works by slowing the reuptake of dopamine in some brain circuits, increasing the amount of dopamine in the synapse. It also blocks serotonin binding in other brain circuits. Based on only this information, you can conclude that this new psychoactive drug is a: dopamine and serotonin antagonist. dopamine antagonist and serotonin agonist. dopamine and serotonin agonist. dopamine agonist and serotonin antagonist.
