Flashcards in Chapter 7: Endocrine System: Hormones Deck (29):
1

Chemical signaling molecules that function systemically, that is, following entrance into the blood.

Hormone

2

Epithelial tissue that releases hormones directly into the blood.

Endocrine gland

3

Localized cell-to-cell communication mediated by intentionally cell-produced molecules.

Paracrine signaling

4

Hormone-like chemicals that are released from the same cell that they act upon.

Autocrine substance

5

Region of the brain that controls the release of hormones by the pituitary gland.

Hypothalamus

6

Hypothalamus-associated gland responsible for releasing numerous hormones including oxytocin and growth hormone.

Pituitary gland

7

Regulator of the reabsorption of water during urine formation such that the urine becomes less dilute.

Antidiuretic hormone

8

Oxytocin

Hormone that affects the functioning of the uterus as well as mammary glands, resulting in contraction of associated smooth muscles.

9

Neck-located gland that produces an iodine-containing hormone that is necessary for maintaining normal metabolic rate, growth, and development.

Thyroid gland

10

Iodine-containing hormone that is necessary for maintaining a normal metabolic rate.

Thyroxine

11

Source of a hormone that has the effect of increasing blood calcium levels when those levels otherwise are low

Parathyroid gland

12

Kidney associated gland responsible for producing the hormones epinephrine and cortisol among others.

Adrenal gland

13

Portion of gland responsible for producing the hormones epinephrine as well as norepinephrine

Adrenal medulla

14

Substance substantially responsible for hormonally effecting fight-or-flight responses.

Epinephrine

15

Gland associated with the production of glucocorticoid hormones as well as the hormone, aldosterone.

Adrenal cortex

16

Diversity of lipid-soluble, blood circulating compounds that resemble in structure the membrane compound, cholesterol.

Steroid hormones

17

Glucocorticoid involved in the regulation of blood glucose levels as well as levels of body stress.

Cortisol

18

Mineralocorticoid involved in the regulation of blood sodium ion and potassium ion levels.

Aldosterone

19

Hormone responsible for stimulating production of new red blood cells.

Erythropoietin

20

Primary producer of androgens by males.

Testes (as endocrine gland)

21

Various primary male sex hormones.

Androgens

22

Primary producer of estrogens by females.

Ovaries (as endocrine gland)

23

Various primary female sex hormones.

Estrogens

24

Glucose

Primary means of blood circulation of chemical energy.

25

Organ responsible for producing insulin in response to high blood glucose levels.

Pancreas (as endocrine gland)

26

Hormone responsible for signaling various cell types to take up excess glucose from the blood.

Insulin

27

Hormone responsible for signaling various cell types to release glucose into the blood.

Glucagon

28

Disease of excessive blood glucose associated with decreased ability to produce insulin.

Diabetes mellitus Type 1

29

Disease of excessive blood glucose associated with decreased ability of cells to respond to insulin.

Diabetes mellitus type 2
