Anterior pituitay Flashcards
What does GnRH do
stimulate LH and FSH
What does dopamine do
inhibit PRL
What does Thyrotropin releasing hormone do
stimulate TSH
what does somatostatin do
inhibits GH
What does CRH (corticotropin releasing hormone) do
Stimulates ACTH
What is the only strictly inhibitory hormone
Dopamine inhibits prolactin
What is FSH
Follicle stimulating hormone
What is LH
luteinizing hormone
What is prolactin
protein produced by acidophils of pituitary
Mammary gland development
Milk production
What is TSH
Thyroid stimulating hormone
What is PRL
Prolactin
What is GH
Growth hormone (somatotropin)
What is ACTH
adrenocorticotropin hormone
What is one key difference between prolactin (besides being inhibited by dopamine) and other hormones
concentrations change during life
What induces prolactin
Suckling
What does prolactin target
milk formation in milk producing cells
What does oxytocin act on
muscle cells
What happens when too much prolactin is produced
Hyperprolactinemia
tumor of adenopypophysis sometimes
Can treat with dopamine like drug
What are examples of glycoprotein hormones
FSH, LH,TSH
What is common for all glycoprotein hormones
Alpha subunit
What is unique to each glycoprotein hormone
beta subunit
What do gonaotropins do
regulate reproductive tract
What does FSH stimulate
Granulosa cells
What does LH stimulate
theca, ovulation, corpus luteum
What does estradiol and progesterone do to the hypothalamus and pituitary glands
Negative feedback to reduce the amount of GnRH produced which lowers the amount of LH and FSH produced
What does anterior pituitary produce
FSH, LH-Repro TSH-Thyroid PRL-Lactation GH-Growth hormone ACTH- adrenocorticotropic
What does GHRH do
stimulates growth hormone
