Growth hormone and thyroid-stimulating hormone are released by which part of the pituitary?

Explanation:
Growth hormone and thyroid-stimulating hormone are released by the anterior pituitary, the part of the pituitary that synthesizes and secretes several hormones in response to hypothalamic releasing and inhibiting signals. The hypothalamus sends GHRH and somatostatin to control growth hormone, and TRH to regulate TSH, but the actual production and release of both hormones occur in the anterior pituitary. The posterior pituitary, by contrast, does not make these hormones; it stores and releases oxytocin and vasopressin that are produced by the hypothalamus. The pineal gland is a separate structure that releases melatonin. So, GH and TSH come from the anterior pituitary.
