Somatotropic
lactotropic

GPA– GH Prolactin Acidophilic

Question 3

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

Answer 3

Somatotropin

Growth of long bones and other growth related processes

Question 4

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

Answer 4

Prolactin

stimulation of milk secretion

Question 5

What cells types are basophilic?

Answer 5

Gonadotropic
Thyrotropic
Corticotropic

B-FLAT—Basophilic FSH LH ACTH TSH

Question 6

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

Answer 6

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

Question 7

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

Answer 7

Thyrotropin(TSH)

stimulation of thyroid hormone secretion

Question 8

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

Answer 8

ACTH and B-lipotropin

ACTH– stimulation of adrenal cortical hormone secretion

B-lipotropin– Promotes utilization of fat

Question 9

What two hormones are released from the posterior pituitary?

Answer 9

Vasopression(ADH)

Oxytocin

Question 10

What is the function of ADH?

Answer 10

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

Question 11

What is the function of Oxytocin?

Answer 11

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

Question 12

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

Answer 12

Zona glomerulosa
Zona fasciculata
Zona reticularis

Question 13

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

Answer 13

Mineralocorticoids–primarily aldosterone

regulation of salt balance

angiotensin II regulates the hormone

Question 14

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

Answer 14

Glucocorticoids– primarily cortisol

regulation of glucose metabolism and is regulated by ACTH

Question 15

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

Answer 15

Cortisol and androgen(DHEA)

glucose regulation and testosterone production regulated by ATCH

Question 16

What hormone is produced by the medulla? and its function

Answer 16

Catecholamines–epi and NE

Fight/flight response regulated by sym NS

Question 17

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

Answer 17

alpha
beta
delta
F/PP

Question 18

What do alpha cells produce and what is its function?

Answer 18

Glucagon– increase blood glucose

Question 19

What do beta cells produce and what is its function?

Answer 19

Insulin– lowers blood glucose

Question 20

What do delta cells produce and what is its function?

Answer 20

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

Question 21

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

Answer 21

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