Endocrine Quiz #2

Front 1

Hormone Secretion Regulation:

Back 1

Normally the secretion of hormones is regulated so there is no overproduction of hormones. Various conditions result if this does not occur.

Front 2

Types of Negative Feedback Systems:

Back 2

1. levels of chemicals in the blood
2. nerve impulses
3. Chemical secretions from the hypothalamus

Front 3

Nerve Impulses

Back 3

stimulate endocrine glands such as the adrenals to release epinephrine/norepinephrine

Front 4

Releasing hormones

Back 4

stimulates the release of hormones from the blood

Front 5

Inhibiting hormones

Back 5

prevents the release of hormones from the blood

Front 6

Pituitary Gland

Back 6

called the "master gland," is a small round structure attached to the hypothalamus, consists of anterior and posterior.

Front 7

4 of the 7 hormones secreted by Pituitary gland

Back 7

Human Growth Hormone, Thyroid Stimulating hormone, Follicle stimulating hormone, melanocyte stiumlating hormone

Front 8

Posterior Pituitary

Back 8

stores and releases hormones made elsewhere including Oxytocin and Antidiuretic hormone

Front 9

oxytocin

Back 9

involved in birth process

Front 10

Thyoid Gland

Back 10

located just below larynx and in front of the trachea. Produces calcitonin

Front 11

Parathyroid Gland

Back 11

posterior of throid gland

Front 12

Parathyroid Hormone

Back 12

controls the level of ca++ and phosphate levels in a different way than calcitonin

Front 13

Adrenal Glands

Back 13

two glands located superior to each kidney. outer part= adrenal cortex. inner part= adrenal medulla. produces important hormones

Front 14

Mineral Corticoids

Back 14

control the homeostasis of water, sodium, and potassium

Front 15

Aldosterone

Back 15

helps regulate blood pH, blood volume, and blood pressue

Front 16

Glucocorticoids

Back 16

concerned with metabolism and resistance to stress. increase the availability of PTH

Front 17

Gonadocorticoids

Back 17

adrenal sex hormone including estrogen and androgens

Front 18

Eprinephrine and Norepinephrine

Back 18

aka adrenaline and noradrenaline. primary hormones of flight-or-fight

Front 19

Pancreas

Back 19

both endocrine and exocrine, located slightly below the stomach, and contains cell clusters called Islets of Langerhans

Front 20

Alpha cells

Back 20

secrete glucagon hormone

Front 21

Beta Cells

Back 21

secrete inculin hormones

Front 22

Glucagon

Back 22

increases your body glucose level to make blood sugar levels rise

Front 23

Insulin

Back 23

decreases blood sugar levels when too high by speeding up conversion of glucose into glycogen

Front 24

Type I diabetes

Back 24

more common under 21, pancrease is destroyed by antibodies and can't make insulin, will always be dependent on insulin, high sugar levels

Front 25

Type II diabetes

Back 25

multifactorial, fewer receptors to br ing insulin/glucose across cell membrane which wears out pancreas. Insulin is not made correctly

Front 26

Ovaries

Back 26

female gonads, produce estrogen and progesterone

Front 27

Teste

Back 27

produce testosteron, controls many behaviors and characteristics

Front 28

Pineal Gland

Back 28

makes melatonin in responses to light/dark cycle exposure

Front 29

Thymus gland

Back 29

Found located behind sternum and between lungs. Makes some cells produce antibodies and helps T-cells mature

Front 30

stressor

Back 30

any disturbance which stimulates the hypothalamus to initiate changes to respond to it
