Hypothalamus
neurons
synthesize oxytocin
and ADH.
2 Oxytocin and ADH are
Inferior
hypophyseal artery
transported along the
hypothalamic-hypophyseal
tract to the posterior
pituitary.
3 Oxytocin and ADH are
stored in axon terminals
in the posterior pituitary.
4 Oxytocin and ADH are
Oxytocin
ADH
released into the blood
when hypothalamic
neurons fire.
