Question Answer
What does "MSH" stand for? Melanin Stimulating Hormone
Where does MSH originate from? Anterior Pituitary Gland
What does MSH do? Acts on skin, protects skin from sunlight. Involved in natural skin colour and tanning.
What does FSH stand for? Follicle Stimulating Hormone
Where does FSH originate from? Anterior Pituitary Gland
What does FSH do in females? Targets the ovaries, and develops and matures egg cell(s) and stimulates estrogen.
What does FSH do in males? Targets the testes (seminiferous tubules), and produces sperm cells.
What does LH stand for? Leutenizing Hormone
Where does LH originate from? Anterior Pituitary Gland
What does LH do in females? Releases egg(s) and stimulates progesterone.
What does LH do in males? Targets testes (the interstitial cells), and produces testosterone.
What does PRL stand for? Prolactin
What does prolactin do? Produces breast milk
What hormone might increase in women after childbirth? Prolactin
What hormone is responsible for releasing breast milk? Oxytocin
What does TSH stand for? Thyroid Stimulating Hormone
What hormone targets the thyroid AND neck? TSH
What does TSH do? Stimulates the thyroid to be more active.
What does ACTH stand for? Adrenaloeorticotropin Hormone
What are the two parts of ACTH? Interior medulla, and outer cortex
What does Alclostone (in ACTH) do? Increase osmotic pressure and blood pressure.
What does Cortisone (in ACTH) do? The breakdown in an immune system, from stress, where an individual may become very ill, however is often used by doctors to reduce swelling)
What does HGH stand for? Human Growth Hormone
What does HGH target? All body cells, but particularly bone cells
Where does HGH originate from? Anterior Pituitary Gland
Where does ACTH originate from? Anterior Pituitary Gland
What does HGH do? Increases bone size and density.
What might happen if not enough HGH is produced? Pituitary Dwarfism may occur (but can be genetic as well)
What does GnRH stand for? Gonadotrophin Releasing Hormone
Is GnRH found in men or women? Men
Where does GnRH originate from? Hypothalamus
What part of the body does GnRH target? Anterior Pituitary Gland
What does GnRH do? Stimulates anterior pituitary gland to secrete FSH and LH.
Is Inhibin found in men or women? Men
What part of the body is targetted by inhibin? Anterior pituitary gland and hypothalamus.
What does Inhibin do? Reduces sperm cell development (decreasing GnRH and FSH), a negative feedback loop to GnRH and FSH.
Where does testosterone originate from? Testes
Is Testosterone found in men or women? Men
What parts of the body are targetted by Testosterone? Muscles, bones, follicular, etc.
What does Testosterone do? Increases secondary male characteristics. Is in complementary feedback with LH.
Is Estrogen found in men or women? Women
Where does Estrogen originate from? Ovary
What does Estrogen target? Uterus
What does Estrogen do? Initiates the development of uterine lining.
Is Progesterone found in men or women? Women
Where does Progesterone originate from? Ovary (corpus luteum)
What does Progesterone target? Uterus
What does Progesterone do? Maintains the lining of the uterus.
