1C - Nervous & Endocrine System

Question 1

What hormones does the hypothalamus secrete

Answer 1

Gonadotropin releasing hormone bracket (GnRH) and thyroid releasing hormone (TRH)

Question 2

What is the function of the gonadotropin releasing hormone GnRH?

Answer 2

GNRH is like a manager in your brain that tells your pituitary gland to release specific hormones which are LH which is luteinizing hormone and FSH, which is follicle stimulating hormone. It is the manager of your reproductive factory and LH and FSH are the workers.

Question 3

What is the function of the thyroid releasing hormone TRH?

Answer 3

TRH is like a manager that instructs the pituitary gland to tell your thyroid gland to start producing hormones to control your metabolism. TRH stimulate the pituitary gland to secrete TSH, which is thyroid stimulating hormone, which, as the name suggests it, stimulates the thyroid to secrete, thyroxin and calcitonin.

Question 4

What is the human growth hormone HGH?

Answer 4

This hormone is in the anterior Tuitt gland and it stimulates cell division bone and muscle growth and metabolic functions, which is how the energy from your food is used

Question 5

Which hormones are secreted from the anterior pituitary gland, which is the front of the pituitary gland.

Answer 5

Human growth hormone, HGH, thyroid stimulating hormone, TSH, adrenocorticotropic hormone ACTH, prolactin PRL, luteinizing hormone, LH and follicle stimulating hormone, which is FSH.

Question 6

What is the function of thyroid stimulating hormone TSH

Answer 6

Stimulate the thyroid gland produced thyroxin and calcitonin

Question 7

What is the function of adrenal corticotropin hormone ACTH?

Answer 7

Stimulates the adrenal cortex of the adrenal glands, which it looks like a little top hat on top of the kidney and it’s the outside of that top hat it stimulates it to secrete glucocorticoids like cortisol, which is long-term stress hormone.

Question 8

What is follicle stimulating hormone FSH?

Answer 8

It stimulates production of over and sperm from the ovaries in testes

Question 9

What is luteinizing hormone LH?

Answer 9

Stimulate sex hormone production from the testes (testosterone) plus ovaries, (estrogen, and progesterone)

Question 10

What is prolactin PRL?

Answer 10

Stimulates milk production from the mammary glands

Question 11

Which hormones are secreted in the posterior pituitary gland which is the back of the pituitary gland?

Answer 11

The antidiuretic hormone, which in short is ADH and oxytocin, which is the love hormone.

Question 12

What is the antidiuretic hormone do in short it is ADH?

Answer 12

ADH promotes the retention of water by kidneys, makes nephron more permeable to water uptake

Question 13

What is oxytocin the love hormone?

Answer 13

Oxytocin stimulates the uterine muscle contractions and release of milk by the mammary glands

Question 14

Which hormones are secreted in the thyroid?

Answer 14

Thyroxine T4, and calcitonin

Question 15

What is the function of a hormone thyroxine T4?

Answer 15

Thyroxin affect all tissue increases, metabolic rate, regulates growth, and development in children

Question 16

What is the function of calcitonin?

Answer 16

Targets, bones and kidneys to lower blood, calcium from bone and reabsorption of calcium by kidneys

Question 17

What hormone is secreted by the parathyroid?

Answer 17

The parathyroid hormone PTH

Question 18

What is the function of the parathyroid hormone PTH?

Answer 18

PTH is supposed to raise calcium levels by stimulating bone cells to release calcium into blood tells intestine to uptake calcium from food and also increase calcium uptake in the kidney. It is an antagonistic hormone to calcitonin meaning it has opposite functions for the same topic.

Question 19

What hormones does the adrenal cortex secrete?

Answer 19

It’s a secret glucocorticoid and aldosterone. Did you know cortex is the outside of the little top hat on top of the kidney not the inside.

Question 20

What is glucocorticoid?

Answer 20

Glucocorticoid stimulates tissues to raise blood glucose and breakdown protein. It is a long-term stress response.

Question 21

What is aldosterone?mineral corticoid?

Answer 21

makes u pee out potassium and retain sodium. Also raise his blood pressure.

Question 22

What hormone does the adrenal medulla secrete?

Answer 22

Epinephrine/adrenaline

Question 23

What is the function of epinephrin the hormone/adrenaline?

Answer 23

Is a fighter flight response as for stress raise his blood glucose it’s a short-term stress response increase heart rate, blood pressure, dilate pupils, and dilate bronchioles to take in more air

Question 24

What hormones does the pancreas which has exocrine and endocrine functions secrete?

Answer 24

Insulin and glucagon

Question 25

What is the function of the hormone insulin?

Answer 25

Insulin lowers blood glucose levels and promotes the formation/storage of glycogen in the liver. Remember that it is used for people, diabetes type one and two.

Question 26

What is the function of glucagon?

Answer 26

Raise blood glucose levels by triggering the liver to breakdown, glycogen and release glucose to the bloodstream. This is also an antagonistic hormone to insulin opposite, but equal functions.

Question 27

What are the hormones released by the ovaries?

Answer 27

Oestrogen and progesterone

Question 28

What is the function of the hormone estrogen?

Answer 28

Stimulates uterine line and growth and promotes development of the female secondary sex characteristics so like writing of the hips development of verse tissue and less body hair than dude I guess

Question 29

What is the function of the hormone progesterone?

Answer 29

Promotes development and maintenance of the uterine lining and prevents urine contraction. Is the pregnancy hormone.

Question 30

What hormone is secreted by the testes?

Answer 30

Testosterone

Question 31

What is the function of the hormone testosterone?

Answer 31

Testosterone promotes sperm formation and development of male secondary sex characteristics, like widening of the shoulders, more body hair deeper voice.

Question 32

non target hormone

Answer 32

targets all cells

Question 33

target hormones

Answer 33

only affects certain cells

Question 34

tropic hormones

Answer 34

hormones that have other endocrine glands as their target. Most tropic hormones are produced and secreted by the anterior pituitary

Question 35

endocrine vs exocrine

Answer 35

endocrine releases hormones directly into the bloodstream, use long distance signalling using these hormones and have two major types, steroid(lipid) and protein based hormones exocrine is when a duct is used, often secreting something into the digestive system.

Question 36

protein hormones

Answer 36

water soluble they're made of proteins, peptides, or amino acids. they bind to receptor sites on the outside of the cells and activates pathways inside the cell

Question 37

steroid hormones

Answer 37

these are lipid soluble meaning that they can slide right through the phospholipid bilayer of cells and bind to receptors inside the cell

Question 38

negative feedback loop

Answer 38

the process by which the end product of a system limits its own production

Question 39

positive feedback loop

Answer 39

the process by which a system's end product enhances its production.

Question 40

which side of the pit. gland does not synthesize its own hormones

Answer 40

posterior, it stores and releases hormones that have been synthesized by the hypothalamus, so like ADH and oxytocin

Question 41

hormones that stimulate endocrine glands to produce other hormones are known as

Answer 41

tropic hormones

Question 42

many hormones are regulated by

Answer 42

negative feedback loops

Question 43

calcitonin does what

Answer 43

acts on bone cells to lower calcium levels in the blood if calcium levels in the blood rise, this hormone causes bones to uptake calcium from the blood
