Hormones & Development Flashcards
exocrine
secreted outside
endocrine
secreted inside
classic endocrine pathway
secretes the hormone into blood stream through blood vessel (secretion comes from ductless glands)
endocrine signaling
a –> b
b - receptor
classic
paracrine signaling
localized effect
ex. within ovary does not need bloodstream to get from place to place
self signaling
out –> onto receptor of same cell
pituitary gland
regulates body function, maintains homeostasis, ‘master gland’
ovaries - estrogen, progesterone
testis - testosterone
fatty acid
dissolve in fats, goes right through membrane
cholesterol derivatives = testosterone & estrogen
protein hormones
water soluble, amino acids
hypothalamus
above pituitary gland
pituitary gland
posterior - neuronal
anterior - glandular, epithelial
posterior pituitary
ADH
oxytocin
anterior pituitary
FSH + LH
TSH
ACTH
Prolactin
MSH
GH
steroids
balding, mania, breast enlargement (M), breast reduction (F), kidney disease, cancer, liver dysfunction, reduction of testis (or ovary swelling), bone density increase,
wolffian duct
male
