What are the hormones involved in the emergency stress response and what secretes them?

Back 2

GH,PRL,ACTH,TSH,LH,FSH,ADH,OT
(E)epinephrine
(NE)norepinephrine
secreted by the adrenal medulla

Front 3

thymosins

Back 3

secreted by: thymus
target: body cells
effect: immune defense by stimulating the development of T-lymphocytes

Front 4

What are the 6 hyperglycemic hormones and their secreting glands?

Back 4

(T4)thyroxine- thyroid

(GH)growth hor.- ant.pituitary

glucagon- pancreas

cortisol- adrenal cortex

(E)epinephrine-adrenal medulla

(NE)norepinephrine-adrenal medulla

Front 5

oxytocin (OT)

*positive feedback

Back 5

secreted by: posterior pituitary
target: mammary and uterus
effect: causes uterine contractions,
RELEASE of milk in mammary glands

Front 6

antidiuretic hormone (ADH)

Back 6

secreted by: posterior pituitary
target: kidney tubules
effect: increases H2O reabsorption

Front 7

luteinizing hormone (LH)

Back 7

secreted by: anterior pituitary
target: gonads (ovaries/testes)
effect: female- stimulates production of est. and prog. causing maturation of follicles and promoting ovulation
male- stimulates the interstitial cells of the testes to produce testosterone

Front 8

follicle stimulating hormone (FSH)

Back 8

secreted by: anterior pituitary
target: gonads (ovaries/testes)
effect: stimulates gamete production

Front 9

thyroid stimulating hormone (TSH)

Back 9

secreted by: anterior pituitary
target: thyroid
effect: stimulates secretion of T3 and T4
increase metabolic rate
heat production
heart rate resp. rate up

Front 10

adrenocorticotropic hormone (ACTH)

Back 10

secreted by: anterior pituitary
target: adrenal cortex
effect: stimulates the adrenal cortex to produce cortisol

Front 11

growth hormone (GH)

Back 11

secreted by: anterior pituitary
target: most body cells
effect: stimulates body cells to increase in size and divide

Front 12

prolactic (PRL)

Back 12

secreted by: anterior pituitary
target: mammary glands
effect: stimulates the PRODUCTION of milk

Front 13

melatonin

Back 13

secreted by: pineal
target: most cells
effect: influences daily rythems, may inhibit reproductive function, may be an antioxident

Front 14

thyroxine (T4)
triiodothyronine (T3)

Back 14

secreted by: thyroid
target: body cells
effect: increases basal metabolic rate and heat production
secreted by: thyroid
target: body cells
effect: increases basal metabolic rate and heat production

Front 15

calcitonin (CT)

Back 15

secreted by: thyroid
target: bone & kidneys
effect: inhibits osteoclasts decreasing Ca2+ concentration which is excreted in the urine

Front 16

parathyroid hormone (PTH)

Back 16

secreted by: parathyroid gland
target: bone and kidneys
effect: increases Ca2+ concentration in fluids by STIMULATING osteoclast activity and promoting absorption of Ca2+ and PO43- by the digestive tract

Front 17

insulin

Back 17

secreted by: pancreas
target: most cells
effect:
***HYPOglycemic regulator- the only hormone that decreases blood glucose levels

Front 18

glucagon

Back 18

secreted by: pancreas
target: liver
effect: breakdown of glycogen into glucose from non-carbohydrates, releases glucose into the blood
**Hyperglycemic regulator- increases blood glucose levels

Front 19

aldosterone

Back 19

secreted by: adrenal cortex
target: kidneys
effect: reabsorption of Na+ and H2O, also loss of K+ or H+

Front 20

cortisol

Back 20

secreted by: adrenal cortex
target: most cells
effect: helps resist stress
**Hyperglycemic regulator- increases blood glucose levels
Anti- inflammatory

Front 21

Adrenal androgens

Back 21

secreted by: adrenal cortex
target: all cells
bone formation, muscle growth

Front 22

epinephrine (E)
(AKA adrenalin)

Back 22

secreted by: adrenal medulla
target: most cells
effect: increases cardiac activity, BP, glycogen breakdown, and release of lipids from adipose
*emergency stress response

Front 23

norepinephrine (NE)

Back 23

secreted by: adrenal medulla
target: most cells
effect: increases cardiac activity, BP, glycogen breakdown, and glucose levels by releasing lipids from adipose
**Hyperglycemic regulator- increases blood glucose levels

Front 24

estrogens

Back 24

secreted by: ovaries, placenta
target: reproductive system
effect: oogenesis, follicle growth, structure growth, 2ndary sex characteristics

Front 25

testosterone

Back 25

secreted by: testes
target: reproductive system
effect: stimulates spermatogenesis, muscle growth, development of 2ndary sex characteristics

Front 26

progesterone (PROG)

Back 26

secreted by: ovaries, placenta
target: uterus, mammary glands
effect: regulates uterine cycle, accelerates movement of the egg, prepares uterus, prepares mammary glands

Front 27

thymosins

Back 27

secreted by: thymus
target: body cells
effect: immune defense by stimulating the development of T-lymphocytes
