Somatostatin, also known as growth hormone-inhibiting hormone (GHIH) or by several other names, is a peptide hormone that regulates the endocrine system and affects neurotransmission and cell proliferation via interaction with G protein-coupled somatostatin receptors and inhibition of the release of numerous secondary hormones. The most important things for the placenta I would say are knowing that it secretes Human Chorionic Gonadotropin to prevent the corpus luteum degradation, and that it later produces the progesterones once produced by the corpus luteum (the goal of both being maintaining the endometrium so you don't continue the menstrual cycle after implantation.)
