Q

what is the role of the hypothalamus in pituitary gland secretions

A

secretes releasing or inhibitory hormones to stimulate or prevent secretion from anterior lobe

17

A

hypothalamic neurones secrete releasing or inhibitory hormones, then hypophyseal portal veins carry hormones to 2nd capillary bed of anterior pituitary
