Endocrine System Flashcards
What’s the hypothalamus’s target?
Anterior pituitary
What’s the action of the hypothalamus and what hormones does it release?
Regulates release of pituitary hormones and hypothalamic releasing hormones
What hormone does the posterior pituitary release?
Antidiuretic hormone (ADH)
What does ADH target and whats its action?
Kidneys and the reabsorbtion of H20
Whats the mechanism controlling secretion for ADH
Hypothalamus (neurons) based on salt balance in blood
Which gland produces TSH (Thyroid stimulating gland)
Anterior pituitary
What is the target of TSH and what’s its action?
Thyroid gland and it’s stimulates the thyroid gland to release thyroxine
What gland secretes ACTH (adrenocorticotropic hormone)
Anterior pituitary
What does ACTH target?
The adrenal cortex
What does ACTH do?
Stimulates the release of cortisol (long term stress)
What does the growth hormone target?
Body cells ( long muscles / bones )
What’s the action of the growth hormone?
Increases cell division (mitosis)
What gland produces growth hormones?
Anterior pituitary
What’s the mechanism controlling secretion for all the hormones in the anterior pituitary?
Releasing hormones from hypothalamus
what hormone does the adrenal medulla secrete?
Epinephrine (adrenaline)
Whats the target of epinephrine and it’s action?
Many body cells and it’s the fight or flight response (short term stress)
What controls the release of epinephrine?
Hypothalamus controls releasing hormones (sympathetic neurons)
What does the adrenal cortex secrete?
Cortisol and aldosterone
What are the targets of cortisol?
Liver and muscle cells
What’s the action of cortisol?
Converts amino acids into glucose, increases blood glucose, and it reduces muscle inflammation
What mechanism controls the release of cortisol?
ACTH stimulates release
What gland secretes aldosterone?
The adrenal cortex
What’s the target of aldosterone?
Kidneys
What’s the action of aldosterone?
Reabsorbtion of Na+ which raises the BP
