Norman ate his birthday cake with lots of sugary frosting, so his pancreas secreted ________.
Anettt [7]

Norman ate his birthday cake with lots of sugary frosting, so his pancreas secreted insulin.

FSH (follicle stimulating hormone) stimulates the production of egg cells in women or sperm in men. A woman's PRL (prolactin) causes the corpus luteum, located in the area around mature follicles, to produce her two key hormones, estrogen, and progesterone.

Growth hormone (GH) or somatotropin, also known as the human form of human growth hormone (HGH or HGH), is a peptide hormone that stimulates growth, cell renewal, and cell regeneration in humans and other animals.

This type of hormone characteristically requires a second messenger. PTH is required to produce calcitriol (activated vitamin D), which is required for calcium transport through cells.
