BIO 202 Exam 1 Questions and Answers 100% Pass Adenohypophysis = _?_ Anterior pituitary ADH and oxytocin are produced in the _?_ and stored in the _?_ Produced in the hypothalamus and stored in the neurohypophysis ADH is also known as _?_ Antidiuretic hormone Adrenergic vs. muscarinic receptor in cardiac pacemaker tissue Parasympathetic hits Muscarinic ACh Muscarinic - slows heart down Since adrenergic stimulation can increase the activity of these channels, this is an explanation for why the risk of sudden death in individuals with LQTS is increased during increased adrenergic states (i.e., exercise, excitement) Anatomical and physiological relationship between the hypothalamus and anterior pituitary. The hypothalamus is just superior to the anterior pituitary Hypothalamus makes the hormones and they are stored and stimulated in the anterior pituitary. ANP and BNP Atrial natriuretic peptide (ANP) Produced by cells in right atrium Brain natriuretic peptide (BNP) Produced by ventricular muscle cells The wall of the atrium releases ANP and the ventricle releses BNP - these two go to the kidneys - tell them to get rid of the sodium (and therefore water) - should decrease his blood pressure Antigens vs antibodies Antigens - unique molecules on cell surface - used to distinguish self from foreign - foreign antigens generate immune response Antibodies - secreted by plasma cells - as part of immune response to foreign matter Arteries vs. veins - anatomical and physiological differences Arteries - strong and thick Veins - smushed, valves Baroreceptros Changes in BP detected by stretch receptors (baroreceptors), in large arteries above heart Aortic arch Carotid sinus (base of each internal carotid artery) Be familiar with the general values found in a CBC, especially, hematocrit, hemoglobin, and WBC count. Complete blood count A LOT MORE RBC (millions) than WBC (thousands) Platelets (hundred thousands) Hematocrit - around 35-55% Hemoglobin - around 12-18 Briefly,
