The _______ Releases GHRH and GHIH to Regulate Growth Hormone

Question

The _______ releases GHRH and GHIH to regulate growth hormone secretion.
A) anterior pituitary
B) posterior pituitary
C) hypothalamus
D) pineal gland

Accepted Answer

The hypothalamus releases two hormones, GHRH (growth hormone-releasing hormone) and GHIH (growth hormone-inhibiting hormone) that regulate the secretion of growth hormone by the anterior pituitary gland. The posterior pituitary gland secretes oxytocin and vasopressin (antidiuretic hormone), while the pineal gland secretes melatonin.
