Growth Hormone Inhibiting Hormone GHIH Anterior pituitary Gland Triggers stop/inhibits release of hGH from Anterior Pituitary Gland Thyrotropin Releasing Hormone TRH Anterior Pituitary Gland Stimulates TSH & Prolactin secretion Corticotropin Releasing Hormone CRH Anterior Pituitary Gland Stimulates ACTH Secretion Gonadotropin-Releasing Hormone GnRH Anterior Pituitary Gland Stimulates LH & FSH secretion Prolactin Releasing Hormone PRH Anterior Pituitary Gland Stimulates PRL Secretion Prolactin Inhibiting Hormone PIH Anterior Pituitary Gland Inhibits PRL Secretion Synthesis: Hypothalamus Secretion: Posterior Pituitary Hormone Target Organ Function Anti-Diuretic Hormone ADH (Vasopressin) Kidneys Water retention & raises BP by vasoconstriction Oxytocin Uterus/Mammary Glands Triggers Contractions & Lactation Synthesis & Secretion: Anterior Pituitary Gland Hormone Target Organ Function Growth Hormone GH (Somatotropin) Liver – Many cells Triggers liver to secrete Insulin-like growth factors IGF’s for protein synthesis, tissue repair, lipid breakdown, and elevated blood glucose. Thyroid-Stimulating Hormone TSH Follicular cells of Thyroid Gland Stimulates synthesis and release of T3 (Triiodothyronine) & T4 (thyroxine) Adrenocorticotropic Hormone ACTH Adrenal Cortex Stimulates secretion of glucocorticoids (Mainly Cortisol) Melanocyte-Stimulating Hormone MSH Brain / melanocytes Induces sleep, and appetite control, skin pigmentation Luteinizing Hormone LH Ovaries & Testes Ovaries- produces estrogen & progesterone, ovulation, formation of corpus luteum Testes – produces testosterone Follicle-Stimulating Hormone FSH Ovaries & Testes Ovaries – maturity of oocyte, estrogen Testes – gamete formation (sperm) Prolactin PRL Mammary Glands Milk Production & Lactation

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
