Oxytocin
What does ADH do in body? - ✔✔(antidiuretic hormone)
Also called vasopressin. Tells kidneys how much water to conserve and retain
Promotes reabsorption of water FROM collecting ducts WHICH receive urine produced b y nephrons
in kidneys
What hormone stimulates the release of milk from the mammary glands - ✔✔oxytocin
What major hormones are secreted from anterior pituitary - ✔✔GH, Prolactin, MSH, TSH, ACTH,
FSH, LH
What major hormones are secreted from anterior pituitary gland? - ✔✔FAMLTPG
1. GH - growth hormone
2. PH - Prolactin
3. MSH - melanocyte stimulating hormone
4. TSH - thyroid stimulating hormone
5. ACTH - adrenocorticotropic hormone
6. FSH - follicle stimulating hormone
7. LH - luteinizing hormone
Which primary endocrine organs are located in the brain? - ✔✔Hypothalamus
pituitary gland
, pineal gland
Why are the neurons in the hypothalamus called neurosecretory cells? - ✔✔Because they are cells
that respond to neurotransmitters & produce hormones
Why do steroid hormones have more of a sustained effect on metabolism of cell than peptide
hormone? - ✔✔Because they can create NEW protein for cell
Why does the endocrine react slower to external stimuli? - ✔✔It takes time for hormones to travel

a chemical produced by one set of cells that affects a different set of cells - ✔✔hormone
Action of peptide hormones - ✔✔1. activate existing enzyme in cell
- tend to act quickly for short period of time
