Final answer:

The anterior pituitary gland is responsible for secreting six hormones crucial for growth, metabolism, and reproduction: GH, PRL, TSH, ACTH, FSH, and LH. These hormones have unique functions in stimulating various bodily processes, and their secretion is regulated by the hypothalamus through a system of releasing and inhibiting hormones.

Step-by-step explanation:

The gland that secretes six hormones which control growth, metabolism, and reproduction is the anterior pituitary. This gland produces growth hormone (GH), prolactin (PRL), thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH). Each hormone has a specific role:

  • GH - Stimulates cellular activities, such as protein synthesis, that promote growth.
  • PRL - Stimulates the production of milk.
  • TSH - Stimulates the thyroid gland to secrete thyroid hormones, which regulates metabolism.
  • ACTH - Promotes the release of steroid hormones by the adrenal cortex.
  • FSH and LH - Regulate the function of the gonads, which are essential in reproduction.

The production of these hormones is controlled by regulatory hormones from the hypothalamus, which sends releasing or inhibiting signals to the anterior pituitary via the hypophyseal portal system.
