Flashcards: ENDOCRINE
Homeostasis
a process of maintaining a constant internal environment within the body
Internal environment
the blood and tissue fluids that surround all body cells
Negative feedback
operate within the human body and detect changes or imbalances in the internal environment and to restore balance
Endocrine gland
secretions released directly into the bloodstream to be transported to their site of action (ductless)
Exocrine gland
secretions into specific cavity
Follicle Stimulating hormone
egg development
Antidiuretic hormone
osmoregulation
Growth Hormone
growth & division
Oxytocin
birth contractions
Prolactin
milk production
Thyroxine
metabolic rate
Adrenalin
increase blood flow to skeletal muscles, increase cell activity reduce blood flow to un-necessary organs
Cortisol
increases release of fats, converts glucose to glycogen, limits inflation (anti stress)
Insulin
stimulates the absorption of glucose
glucagon
stimulates the conversion of glycogen to glucose
Estrogen / progesterone
menstrual cycle
Testosterone
male characteristics
Hormone
organic chemical messengers
Thyroid stimulating hormone
stimulates secretion of thyroxine
Luteinizing hormone
stimulates ovulation, stimulates testosterone production
ACTH adrenocorticotropic hormone
stimulates the adrenal gland to produce adrenalin and cortisol
Cretinism
caused by severe hypothyroidism in infants
Hyperglycemia
glucose remains in the blood instead of being absorbed
Inhibin
stops the release of FSH
Gonadotrophin
causes the release of LH and FSH
