Flashcards in Hormones by Physiological Effect Deck (25):
1

Insulin

Responds to high glucose levels to bring them down

Secreted from the pancreas (beta cells)

2

Glucagon

Responds to low glucose levels to elevate them

Secreted from pancreas (alpha cells)

3

Cortisol

Responds to stress (long-term), raises glucose levels

Secreted from adrenal cortex, also steroid hormone

4

Epinephrine and Norepinephrine

Responds to stress (short-term), raises glucose levels

Secreted from adrenal medulla, amino acid derived (polar)

5

Growth Hormone (GH)

Responds to stress and growth, raises glucose levels

Secreted from anterior pituitary

6

Parathyroid Hormone (PTH)

Responds to low calcium levels, acts to raise calcium levels

Secreted from parathyroid

7

Calcitonin

Responds to high calcium levels, acts to lower calcium levels

Secreted from thyroid

8

Aldosterone

Responds to low BP, high osmolarity, angiotensin II

Causes increased Na+ reabsorption in DCT and increased fluid levels

Secreted by adrenal cortex

9

ADH (vasopressin)

Responds to low BP, high osmolarity

Causes increases H20 absorption in collecting duct

Secreted by posterior pituitary

10

ANP

Responds to high blood volume causes decreased Na+ reabsorption in DCT, and lower fluid levels

Secreted by heart muscle cells

11

T3 and T4

Responds to TSH, causes an increase in basal metabolic rate

Secreted by the thyroid, amino acid derived (non-polar)

12

Estrogen

Responds to LH, causes female secondary sex characteristics

Secreted by the ovaries, steroid hormone

13

Testosterone

Responds to LH, causes male secondary sex characteristics

Secreted by testes, steroid hormone

14

Progesterone

Responds to hCG, prepares and maintains uterus for pregnancy

Secreted by ovaries and placenta, steroid hormone

15

Luteinizing hormone (LH)

Tropic
Responds to GnRH or low levels of testosterone/estrogen

Causes testosterone/estrogen to increase

Secreted by anterior pituitary

16

Follicle-stimulating hormone (FSH)

Tropic
Responds to GnRH, causes follicle development, spermatogenesis

Secreted by anterior pituitary

17

Human chorionic gonadotropin (hCG)

Tropic
Responds to implantation, causes increase in progesterone

Secreted by placenta

18

Prolactin

Responds to low levels of dopamine, causes milk production

Secreted by anterior pituitary

19

Oxytocin

Responds to neural signaling, uterine stretching and nipple stimulation

Causes contractions (example of positive feedback)

Secreted by posterior pituitary

20

Thyroid Stimulating Hormone (TSH)

Responds to TRH, causes increase in thyroid hormones

Secreted by anterior pituitary

21

Adrenocorticotropic hormone (ACTH)

Responds to CRF, causes increase in adrenal cortex activity (increase in corticosteroids)

Secreted by anterior pituitary

22

Gonadotropin Releasing Hormone (GnRH)

Responds to neural signaling, causes increased LH and FSH

Secreted by hypothalamus

23

Thyrotropin Releasing Hormone (TRH)

Responds to neural signaling, causes increase in TSH

Secreted by hypothalamus

24

Corticotropin Releasing Factor (CRF)

Responds to neural signaling in response to stress, causes increase in ACTH

Secreted by hypothalamus

25

Growth Hormone Releasing Hormone (GHRH)

Responds to neural signaling, causes increase in GH

Secreted by hypothalamus
