Hormones

Question 1

peptide hormones

Answer 1

hormones produced by mRNA translation, released by vesicles

Question 2

steroid hormones

Answer 2

derived from cholesterol and produced on demand

Question 3

adrenal gland

Answer 3

adrenal cortex + adrenal medulla

Question 4

what does the adrenal cortex secrete

Answer 4

steroid hormones

Question 5

what does the adrenal medulla secrete

Answer 5

catecholamines

Question 6

amine hormones

Answer 6

hormones derived from tyrosine

Question 7

glucocorticoid receptor

Answer 7

moves into nucleus when bound to cortisol, causes gene expression there

Question 8

posterior pituitary

Answer 8

neural tissue, releases vasopressin and oxytocin

Question 9

anterior pituitary

Answer 9

endocrine cells, secretes mostly trophic hormones

Question 10

cortisol

Answer 10

tells body to be active

Question 11

long-loop negative feedback

Answer 11

hormone is the feedback signal

Question 12

short-loop negative feedback

Answer 12

pituitary hormone surpresses the hypothalamus

Question 13

hyposecretion

Answer 13

deficient hormone, absence of negative feedback can cause overproduction of trophic hormones

Question 14

hypersecretion

Answer 14

excess hormone, caused by for example tumours

Question 15

hypercortisolism

Answer 15

excess of cortisol may lead to adrenal atrophy

Question 16

hypocortisolism

Answer 16

inadequate cortisol levels, can be caused by adrenal insufficiency or deficit in enzymes

Question 17

thyroid

Answer 17

control growth and metabolism, produce thyroid hormones in presence of iodine

Question 18

hypothyroidism

Answer 18

primary is caused by lack of iodine

Question 19

hyperthyroidism

Answer 19

excess secretion by thyroid gland

Question 20

synergism

Answer 20

the effect of interacting hormones is more than additive

Question 21

permissive

Answer 21

hormone allows other hormone to excert its full effect

Question 22

antagonistic

Answer 22

hormones have opposing effects
