Flashcards in Chap 18, Endocrine System, Vocabulary, Hormones Deck (26)
1

adrenaline (epinephrine)

Secreted by the adrenal medulla; increases heart rate and blood pressure (sympathomimetic)

2

adrenocorticotropic hormone (ACTH); also called adrenocorticotropin

Secreted by the anterior lobe of the pituitary gland (adenohypophysis). ACTH stimulates the adrenal cortex.

3

aldosterone (mineralocorticoid)

Secreted by the adrenal cortex; increases salt (sodium) reabsorption.

4

androgen

Male hormone secreted by the testes and to a lesser extent by the adrenal cortex; testosterone is an example.

5

antidiuretic hormone (ADH) (vasopressin)

Secreted by the posterior lobe of the pituitary gland (neurohypophysis). ADH increases reabsorption of water by the kidney.

6

calcitonin

Secreted by the thyroid gland; decreases blood calcium levels.

7

cortisol

Secreted by the adrenal cortex; increases blood sugar. It is secreted in times of stress and has an anti-inflammatory effect.

8

epinephrine (adrenaline)

Secreted by the adrenal medulla; increases heart rate and blood pressure and dilates airways (sympathomimetic). It is a part of the body's "fight or flight" reaction.

9

estradiol

Estrogen (female hormone) secreted by the ovaries.

10

estrogen

Female hormone secreted by the ovaries and to a lesser extent by the adrenal cortex. Examples are estradiol and estrone.

11

follicle-stimulating hormone (FSH)

Secreted by the anterior lobe of the pituitary gland (adenohypophysis). FSH stimulates hormone secretion and egg production by the ovaries and sperm production by the testes.

12

glucagon

Secreted by alpha islet cells of the pancreas; increases blood sugar by conversion of glycogen (starch) to glucose.

13

growth hormone (GH); somatotropin (STH)

Secreted by the anterior lobe of the pituitary gland (adenohypophysis); stimulates growth of bones and soft tissues.

14

insulin

Secreted by beta cells of the pancreas. Insulin helps glucose (sugar) to pass into cells, and it promotes the conversion of glucose to glycogen.

15

luteinizing hormone (LH)

Secreted by the anterior lobe of the pituitary gland (adenohypophysis); stimulates ovulation in females and testosterone secretion in males.

16

norepinephrine (noradrenaline)

Secreted by the adrenal medulla; increases heart rate and blood pressure (sympathomimetic). Nor- in chemistry means a parent compound from which another is derived.

17

oxytocin (OT)

Secreted by the posterior lobe of the pituitary gland (neurohypophysis); stimulates contraction of the uterus during labor and childbirth.

18

parathormone (PTH); aka parathyroid hormone

Secreted by the parathyroid glands; increases blood calcium.

19

progesterone

Secreted by the ovaries; prepares the uterus for pregnancy.

20

prolactin (PRL)

Secreted by the anterior lobe of the pituitary gland (adenohypophysis); promotes milk secretion.

21

somatotropin (STH) (growth hormone, GH)

Secreted by the anterior lobe of the pituitary gland (adenohypophysis); stimulates growth of bones and soft tissues.

22

testosterone

Male hormone secreted by the testes.

23

thyroid-stimulating hormone (TSH); thyrotropin

Secreted by the anterior lobe of the pituitary gland (adenohypophysis). TSH acts on the thyroid gland to promote its functioning.

24

thyroxine (T4) (tetraiodothyronine)

Secreted by the thyroid gland, T4 increases metabolism in cells.

25

triiodothyronine (T3)

Secreted by the thyroid gland; T3 increases metabolism in cells.

26

vasopressin, [antidiuretic hormone, (ADH)]

Secreted by the posterior lobe of the pituitary gland (neurohypophysis) vasopressin increases water reabsorption and raises blood pressure.
