Question

As an example of hormonal communication, when osmoreceptors of the _______________ detectdehydration, a signal to the posterior pituitary gland causes the release of _________________.A. Hypothalamus: Antidiuretic hormone (ADH)B. Anterior pituitary: Antidiuretic hormoneC. Hypothalamus: OxytocinD. Anterior pituitary: Renin

Answer 1

Answer:

A - Hypothalamus and Antidiuretic Hormones
