Flashcards in Endocrine Deck (21):
What are the two cells of Chromophils? and where are they in the body?
What cell types are Acidophilic?
GPA-- GH Prolactin Acidophilic
What hormone is produced by Somatotropic cells? what is its function?
Growth of long bones and other growth related processes
What hormone is produced by lactotropic cells? what is its function?
stimulation of milk secretion
What cells types are basophilic?
B-FLAT---Basophilic FSH LH ACTH TSH
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
What hormone is produced by Thyrotropic cells? what is its function?
stimulation of thyroid hormone secretion
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
What two hormones are released from the posterior pituitary?
What is the function of ADH?
Regulation of blood osmolarity--increased water reabsorption in kidney collecting ducts
What is the function of Oxytocin?
Stimulation of uterine contraction during childbirth and contraction of my epithelial cells of mammary glands during nursing
What are the 3 regions of the Cortex of the Adrenal gland?
What hormone does the zone glomerulosa produce and whats its function?
regulation of salt balance
angiotensin II regulates the hormone
What hormone does the zone fasciculata produce and whats its function?
Glucocorticoids-- primarily cortisol
regulation of glucose metabolism and is regulated by ACTH
What hormone does the zone reticularis produce and whats its function?
Cortisol and androgen(DHEA)
glucose regulation and testosterone production regulated by ATCH
What hormone is produced by the medulla? and its function
Catecholamines--epi and NE
Fight/flight response regulated by sym NS
What are the 4 cell types of the islets of Langerhans?
What do alpha cells produce and what is its function?
Glucagon-- increase blood glucose
What do beta cells produce and what is its function?
Insulin-- lowers blood glucose
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
