Pituitary Gland & Hypothalamus Flashcards
The hypothalamus regulates pituitary gland activity through:
hormones & action potentials
How many hormones does the pituitary gland secrete?
9
Hypothalamus is connected to pituitary via the:
infundibulum
Posterior/neurohypophysis
store hormones secreted by hypothalamus
ADH & OXYTOCIN
Anterior/adenohypophysis
controls release of hormones produced by the anterior pituitary
Hypothalamohypophyseal portal tract connects the hypothalamus & the:
pituitary gland
Posterior
hormones released are produced in:
hypothalamic neurons in hypothalamus
the hormones moves down the axons of the hypothalamohypophyseal tract & are secreted from the posterior & eventually reach bloodstream
Anterior
hormones produced by hypothalamic neurons act on:
cells of anterior pituitary
through the portal system the inhibit (act as inhibiting hormones) or stimulate (act as releasing hormones) hormone production
