Chapter 44.5, Problem 3CC
Summary Introduction
To identify: The major symptom of the disorder in Conn’s syndrome, leading to an increase in the production of the aldosterone from the adrenal gland.
Concept introduction: The constriction of the blood capillaries is caused by the angiotensin hormone. It causes the increase in the blood pressure inside the vessels. The adrenal gland releases the aldosterone by the action of the hormone angiotenin II. The release of the hormone aldosterone causes the reabsorption of the sodium ions and water in the collecting duct.

. Lipid-soluble signaling molecules, such as aldosterone,cross the membranes of all cells but affect only target cellsbecause(A) only target cells retain the appropriate DNA segments.(B) intracellular receptors are present only in target cells.(C) only target cells have enzymes that break downaldosterone.(D) only in target cells is aldosterone able to initiate thephosphorylation cascade that turns genes on
6. Increasing the aldosterone secretion during prolonged muscle activity in hot
weather allows you to compensate for the sodium loss in sweat and remove
the accumulated excess of potassium. Explain these biological effects of the
hormone during exercise. For answer:
a) draw the structure of the hormone, name the precursor for its synthesis, site
of synthesis, signals for secretion, target cells;
b) draw a diagram of the hormonal signal transduction starting with hormone
interaction with the cell receptor;
7. Mapping exercise: Create a reflex map with feedback loops for each of the following situations:
a. hypercortisolism from adrenal tumor
b. hypercortisolism from pituitary tumor
c. hypothyroidism from hormone-secreting thyroid tumor
d. hypothyroidism from the pituitary problem that decreases TSH synthesis

Correct cause-and-effect relationships following insulin withdrawal in a person with diabetes mellitus include: the ratio of K+ concentration inside the cell to K+ concentration outside the cell decreases in untreated diabetes for multiple reasons, including intracellular H+ buffering, which results in a shift of K+ to the extracellular compartment. ketonemia does not increase urine flow because it is entirely reabsorbed in the renal tubule urinary phosphate decreases because renal excretion of H+ results in increased phosphate reabsorption. serum sodium rises because of fluid shift from the extracellular compartment to intracellular compartment. glomerular filtration rate increases as a result of increased serum glucose concentration. The most effective direct stimulus for the release of glucagon is: an increase in serum glucose an decrease in serum glucose somatostatin insulin (direct action on the…arrow_forward
