Q

THYROID GLAND:

Name the hormones produced by the thyroid gland

A

Thyroxine (T4)
Triiodothronine (T3)
Calcitonin

20
Q

THYROID GLAND:

Where are Thyroxine (T3) and Triiodothronine (T4) stored?

A

thyroid gland

21
Q

THYROID GLAND:

what is a follicle?

A

A follicle is spherical, and the wall is made up of a large number of cuboidal cells. These are the strucutural and functional units of a thyroid gland.

22
Q

THYROID GLAND:

which cells make calcitonin?

A

parafollicular cells (c-cells)

23
Q

PARATHYROID GLAND:

where are the parathyroid glands located?

A

The parathyroid glands are on the posterior surface of the thyroid gland, separated by a capsule.

24
Q

PARATHYROID GLAND:

how many parathyroid glands do you have?

A

4

25
Q

PARATHYROID GLAND:

what is the function of parathyroid hormone? explain

A

The function of the parathyroid hormone is to maintain Ca2+ in the body to maintain homeostasis.
If there is a decrease in Ca2+ levels in the blood, the parathyroid glands secrete parathyroid hormone. This causes increased reabsorption of Ca2+ by kidneys, calcium release from bone, and increased calcitriol production causes Ca2+ absorption by the digestive tract. The Ca2+ levels increase and homeostasis is restored.

26
Q

ADRENAL GLAND:

outer zone: zona__________ stimulates __________

A 
zonaglomerulosa 
mineralocrticoids (aldosterone)
27
Q

ADRENAL GLAND:

middle zone: zona _____________ stimulates___________

A

zonafasciculata

glucocorticoids (cortisol)

28
Q

ADRENAL GLAND:

inner zone: zona ______________ stimulates ____________-

A

zonareticular

androgens (sex hormones)

29
Q

ADRENAL GLAND:

adrenal medulla: releases _________ upon stimulation by the ___________

A

epinephrine and norepinephrine

sympathetic neural axons

30
Q

PANCREAS:

what % of the pancreas is endocrine?

A

2%

31
Q

PANCREAS:

these hormones regulate blood ________

A

glucose (sugar)

32
Q

PANCREAS:

Name the different cells in the Islets of Langerhans and name the hormones produced by those cells.

A

alpha cells secrete glucagon
beta cells secrete insulin
delta cells secrete somatostatin

33
Q

PANCREAS:

Insulin and Glucagon are antigonistic in function. explain.

A

opposite in function
insulin: decreases the level of glucose in blood
converts glucose into glycogen
glucagon: increases the level of glucose in blood
converts glycogen into glucose

34
Q

name two other hormones that are antagonistic in function.

A

parathyroid hormone and calcitonin
parathyroid hormone: is secreted when Ca2+ levels are too low
calcitonin: is secreted when Ca2+ levels are too high
