Question

What stimulates the release of ADH and oxytocin from the posterior pituitary?

a. Hypothalamic hormones
b. Anterior pituitary hormones
c. Neural signals
d. Thyroid hormones

Answer 1

ADH and oxytocin release from the posterior pituitary gland is stimulated by neural signals from the hypothalamus.

Step-by-step explanation:

The release of antidiuretic hormone (ADH) and oxytocin from the posterior pituitary gland is primarily stimulated by neural signals from the hypothalamus. Both ADH and oxytocin are synthesized by the hypothalamic neurons and then transported down the axons to the posterior pituitary. They are stored there until the hypothalamus sends neural signals for their release into the circulatory system. It's important to note that the posterior pituitary does not synthesize these hormones but acts as a storage and release site.
