Flashcards in Endocrine Deck (21):
1

What are the two cells of Chromophils? and where are they in the body?

basophils
acidophils

Anterior pituitary

2

What cell types are Acidophilic?

Somatotropic
lactotropic

GPA-- GH Prolactin Acidophilic

3

What hormone is produced by Somatotropic cells? what is its function?

Somatotropin
Growth of long bones and other growth related processes

4

What hormone is produced by lactotropic cells? what is its function?

Prolactin
stimulation of milk secretion

5

What cells types are basophilic?

Gonadotropic
Thyrotropic
Corticotropic

B-FLAT---Basophilic FSH LH ACTH TSH

6

What hormone is produced by Gonadotropic cells? what is its function?

FSH and LH
FSH-- stimulation of gametogenesis
LH-- regulation of estrogen and androgen secretion promoting ovulation

7

What hormone is produced by Thyrotropic cells? what is its function?

Thyrotropin(TSH)
stimulation of thyroid hormone secretion

8

What hormone is produced by Corticotropic cells? what is its function?

ACTH and B-lipotropin

ACTH-- stimulation of adrenal cortical hormone secretion

B-lipotropin-- Promotes utilization of fat

9

What two hormones are released from the posterior pituitary?

Vasopression(ADH)
Oxytocin

10

What is the function of ADH?

Regulation of blood osmolarity--increased water reabsorption in kidney collecting ducts

11

What is the function of Oxytocin?

Stimulation of uterine contraction during childbirth and contraction of my epithelial cells of mammary glands during nursing

12

What are the 3 regions of the Cortex of the Adrenal gland?

Zona glomerulosa
Zona fasciculata
Zona reticularis

13

What hormone does the zone glomerulosa produce and whats its function?

Mineralocorticoids--primarily aldosterone

regulation of salt balance

angiotensin II regulates the hormone

14

What hormone does the zone fasciculata produce and whats its function?

Glucocorticoids-- primarily cortisol

regulation of glucose metabolism and is regulated by ACTH

15

What hormone does the zone reticularis produce and whats its function?

Cortisol and androgen(DHEA)

glucose regulation and testosterone production regulated by ATCH

16

What hormone is produced by the medulla? and its function

Catecholamines--epi and NE

Fight/flight response regulated by sym NS

17

What are the 4 cell types of the islets of Langerhans?

alpha
beta
delta
F/PP

18

What do alpha cells produce and what is its function?

Glucagon-- increase blood glucose

19

What do beta cells produce and what is its function?

Insulin-- lowers blood glucose

20

What do delta cells produce and what is its function?

Somatostatin-- inhibits release of other islet cell hormones also inhibits release of GH and TSH and HCl secretion from the parietal cells

21

What do F/PP cells produce and what is its function?

Pancreatic polypeptide-- stimulates the activity of gastric chief cells and inhibits bile and pancreatic enzyme secretion
