Question

Test your knowledge of the physiological functions and characteristics of T3 and T4 versus those of cortisol, secreted at basal levels during nonstress situations, by classifying the following statements at left with the correct hormone at right. T and T Cortisol Has permissive acions in reactivity to epinephrine and norepinephrine of smooth muscle cells that surround blood vessels Needed for normal production of growth hormone Increases metabolic rate and thus promotes calorie consumption Classified as a steroid hormone and binds to intracellular receptors Actions cause heat immune functions Classified as an amine hormone and binds to intracellular receptors Allows for proper differentation of parts of brain, adrenal medulla intestines, and lungs in fetal and neonatal development Important for nervous system development during fetal life Maintains concentrations of hepatic enzymes that prevent hypoglycemia between meals Maintains normal blood pressure

Explanation / Answer

Hi,
T3,T4
Increases metabolic rate and thus promotes calorie consumption.
Classified in aminoe hormone and bins to intracellular receptor
Has permissive action in reactivity to epinephrin and norepinephrine of smooth muscle cells that surround blood vessels.
Action causes heat production
Allows for proper differentiation of parts of bain, adrenal medula, intestine and lungs in fetal and nonfetal development.
Needed for normal production of growth hormone.
Important for nervou system development during fetal life.

Cortisol:
Maintains the normal blood pressure.
Anti-inflamatory immne functions.
Classified as steroid hormone and bins to intracellular receptors
Maintains concentrations of hepatic enzymes that prevent hypoglycemia between meals.
