Growth hormone:
promotes long bone growth during the formative years
is also called somatostatin
is regulated by humoral mechanisms
secretion results in decreased muscle mass
is only present in the fetus
a promotes long bone growth during the formative years
All of the following pituitary hormones are released in response to hypothalamic releasing hormones EXCEPT
antidiuretic hormone
growth hormone
thyroid-stimulating hormone
adrenocorticotropic hormone
follicle-stimulating hormone
antidiuretic hormone
Aldosterone
increases sodium reabsorption
decreases sodium reabsorption
increases the blood concentration of potassium
is secreted by the neurohypophysis
increases urine production
increases sodium reabsorption
The hypothalamic-hypophyseal tract:
connects the hypophyseal to the pituitary gland
is the site of prolactin synthesis
is partly contained in the infundibulum
is in the bladder
conducts aldosterone to the hypophysis
is partly contained in the infundibulum
Which of the following physiological processes is controlled by positive feedback
control of blood pressure
regulation of blood sugar
maintenance of body temperature
initiation of blood clotting
control of breathing rate
initiation of blood clotting
Regulating hormones from the hypothalamus
travel by arteries to the pituitary
only affect the brain
enter the hepatic portal system, which feeds the pituitary
enter the venous circulation and travel to the heart first
first enter the hypophyseal portal system
first enter the hypophyseal portal system
