endocrine system Flashcards
what is the endocrine system
glands and tissues that secretes hormones directly to blood
hormones influence
metabolism of cells
growth and development of body parts
homeostasis
endocrine glands
ductless, secrete hormones into tissues then they diffuse into the bloodstream
exocrine glands
have ducts to let the secretion like: sweat glands
which are all the glands
pituitary, pienal, thyroid, adrenal, pancreas, gonads, thymus
pituitary
divided in posterior and anterior, located in the brain
posterior pituitary
ADH (antidiureic hormone): water reabsorption of kidneys
Oxytocin: happy hormone, uterine contractions
anterior pituitary gland
- TSH: thyroid stimulating
- ACTH: Adrenocortiocotropic, stimulate adrenal cortex
- FSH/LH: Gonadotrophic, produce esterogen and testosterone
- PRL: Prolactin, mammary glands
- MSH: Melanocytes
- GH: Growth hormone, bone muscle growth
pineal glands
located in the brain, wake/sleep cycles. Decreases secretion in light MELATONIN
Thyroid gland
secretes thyroxine
Parathyroid
PTH: parathyroid hormone, increase blood calcium and decrease blood phosphate
adrenal gland divisions
adrenal cortex, adrenal medulla
adrenal cortex
glococorticoids: regulate carbohydrate, protein and fat
pancreas
insulin
glucagon
goands
testes
ovaries
