Lab 10: Part 1 - The Pituitary Gland Flashcards
The ANTERIOR PITUITARY GLAND is also known as the…
…ADENOHYPOPHESIS
What does the TSH stand for? What is the target tissue?
THYROID STIM. HORMONE, the thyroid
What does tropic mean?
Tropic HORMONES turn on other ENDOCRINE GLANDS to release more/other HORMONES
Is TSH tropic?
Yes
What is the F of TSH?
F - Stim. thyroid to produce/release hormones
What does ACTH stand for? What is the target tissue?
ADRENOCORTICOTROPIC HORMONE, the adrenal cortex
Is ACTH tropic?
Yes
What is the F of ACTH?
F - Stim. adrenal cortex to release HORMONES
What does PRL stand for? What is the target tissue?
PROLACTIN, mammary glands
Is PRL tropic?
No
What is the F of PRL?
F - Milk production
What does MSH stand for? What is the target tissue?
MELANOCYTE STIM. HORMON, epidermal melanocytes
Is MSH tropic?
No
What is the F of MSH?
F - Promotes epidermal pigment and production of melanin
What does FSH stand for? What is the target tissue in females? Males?
FOLLICLE STIM. HORMONE
Females = Ovarian follicle
Males = Seminiferous tubules
Is FSH tropic in females? Males?
Females = Yes Males = No
What is the F of FSH in females? Males?
Females = Egg development Males = Sperm development
What does LH stand for? What is the target tissue in females? Males?
LUTEINIZING HORMONE
Females = Ovarian follicle
Males = Interstitial cells
Is LH tropic in females? Males?
Females = Yes Males = Yes
What is the F of LH in females? Males?
Females = Stim. ovulation and production of sex HORMONES Males = Production of sex HORMONES
What does GH stand for? What is the target tissue?
GROWTH HORMONE, all cells, especially BONE, MUSCLE, and liver
Is GH tropic?
Yes
What is the F of GH?
F - Stim. nutrient breakdown for growth/cell division, stim. protein synthesis
The POSTERIOR PITUITARY GLAND is also known as…
…the NEUROHYPOHESIS
What does OT stand for? What is the target tissue(s)?
OXYTOCIN, mammary glands and uterine smooth muscle
Is OT tropic?
No
What is the F of OT?
F - Mammary gland = Stim. milk ejection
F - Uterine smooth muscle = Stim. uterine contraction to return to regular size
What does ADH stand for? What is the target tissue?
ANTI DIURETIC HORMONE, kidneys
Is ADH tropic?
No
What is the F of ADH?
F - Inc. water retention/reabsorption, vasoconsriction
What is the role of the HYPOTHALAMUS in regulating PITUITARY function?
The HYPOTHALAMUS releases tropic HORMONES, so it triggers the release or inhibition of HORMONES in the ANTERIOR or POSTERIOR PITUITARY GLAND. The HYPOTHALAMUS produces and release OT and ADH by firing APs
