Question

Nina is researching hormones that can stimulate and inhibit the release of growth hormone from the anterior pituitary. Predict the type of stimulation that regulates the secretion of growth hormone.

1) neural stimulation
2) cellular stimulation
3) humoral stimulation
4) hormonal stimulation

Answer 1

Growth hormone secretion from the anterior pituitary is regulated by hormonal stimulation, involving a feedback loop between the hypothalamus and anterior pituitary.

Step-by-step explanation:

The type of stimulation that regulates the secretion of growth hormone from the anterior pituitary is primarily hormonal stimulation. The hypothalamus produces growth hormone-releasing hormone (GHRH), which stimulates the anterior pituitary to secrete growth hormone (GH). GH secretion is modulated through a negative feedback loop involving the inhibitory hormone somatostatin, also produced by the hypothalamus, which prevents the over-secretion of GH.
