- Pearl is a 45 year old lady with a history of Bipolar Affective Disorder. In the past ten years she has gained a considerable amount of weight (10 years ago she weighed 80kg and now she weighs 130kg). She has been complaining of chest pain and describes it as tightness in her chest. A) Explain your understanding of the cardiac system. B) Why might Pearl's diagnosis of Bipolar Affective Disorder and the weight gain be important to consider in explaining her current presentation?

- Alpha adrenergic antagonists compete with endogenous catecholamines for binding at alpha- 1 and alpha -2 receptors. Because norepinephrine and epinephrine cannot bind to a receptor that is occupied by an antagonist, the actions of catecholamines are inhibited.

She has tried OTC antacids in the past, but did not like them. Instead, she has seen Nexium tablets advertised and wants to know if they would be suitable. Is this an appropriate choice of OTC treatment? Explain in detail and based on scientific reasoning.arrow_forward
- Which of the following statements is true? Chemical messengers within cells are always the main determinant of the effector response. Dual innervation is always present in all organs and glands; one branch enhances the function or secretion, while the other branch inhibits it. The beating of the heart is regulated only by the sympathetic division. Some blood vessels contain alpha adrenergic receptors that cause vasoconstriction in the presence of epinephrine, whereas others have beta adrenergic receptors that cause vasodilation in the presence of epinephrine.arrow_forwardDraw a schematic diagram of the spinothalamic pathway and annotate it by indicating where and how the different drugs workarrow_forwardWhat is stimulants?arrow_forward
