Q

releasing hormones

A

hormones; promote or inhibit release of various hormones by pituitary gland

2
Q

thyroid-stimulating hormone (TSH)

A

anterior pituitary; stimulates thyroid gland

3
Q

luteinizing hormone (LH)

A

anterior pituitary; increases production of progesterone (female), testosterone (male), stimulates ovulation

4
Q

follicle-stimulating hormone (FSH)

A

anterior pituitary; increases production of estrogen and maturation of ovum (female) and sperm production (male)

5
Q

ACTH

A

anterior pituitary; increases secretion of steroid hormones by adrenal gland

6
Q

prolactin

A

anterior pituitary; increases milk production

7
Q

growth hormone (GH) / somatotropin

A

anterior pituitary; increases body growth, including the growth spurt during puberty

8
Q

oxytocin

A

posterior pituitary; controls uterine contractions, milk release, certain aspects of parental behaviour, and sexual pleasure

9
Q

vasopressin (antidiuretic hormone)

A

posterior pituitary; constricts blood vessels and raises blood pressure, decreases urine volume

10
Q

melatonin

A

pineal gland; increases sleepiness, influences sleep-wake cycle, also has a role in onset of puberty

11
Q

thyroxine

A

thyroid gland; increases metabolic rate, growth, and maturation

12
Q

triiodothyronine

A

thyroid gland; increases metabolic rate, growth and maturation

13
Q

parathyroid hormone

A

parathyroid gland; increases blood calcium and decreases potassium

14
Q

aldosterone

A

adrenal cortex; reduces secretion of salts by the kidneys

15
Q

cortisol, corticosterone

A

adrenal cortex; stimulates liver to elevate blood sugar, increase metabolism of proteins and fats

16
Q

epinephrine, norepinephrine

A

adrenal medulla; similar to effects of sympathetic nervous system

17
Q

insulin

A

pancreas; increases entry of glucose to cells and increases storage as fats

18
Q

glucagon

A

pancreas; increases conversion of stored fats to blood glucose

19
Q

estrogens

A

ovary; promote female sexual characteristics

20
Q

progesterone

A

ovary; maintains pregnancy

21
Q

androgens

A

testis; promote sperm production, growth of pubic hair, and male sexual characteristics

22
Q

somatomedins

A

liver; stimulate growth

23
Q

renin

A

kidney; converts a blood protein into angiotensin, which regulates blood pressure and contributes to hypovolemic thirst

24
Q

thymosin (and others)

A

thymus; support immune responses

25
Q

leptin

A

fat cells; decreases appetite, increases activity, necessary for onset of puberty
