c.ii.This gland is releases a ton of hormones that has an effect on a lot of the other glands of the body c.iii.We find out that hypothalamus controls pituitary gland thus it is not a master gland. c.iv.ADH c.iv.1.Antidiaretic hormone c.iv.2.It prevents diaresis (prevents excessive water loss in the urine) c.iv.3.Causes kidney to dump water in the urine, thus blood volume goes down, blood pressure goes down. c.v.Region of the brain that controls pituitary glandc.v.1.Hypothalamus c.vi.Hypothalamus control c.vi.1.Endocrine communication c.vi.1.a.Cells in the hypothalamus goes to the cells in the pituitary gland c.vi.2.Neural communication c.vi.2.a.Nerves in the hypothalamus goes to the pituitary gland secrete hormones 4.The Pituitary Gland a.Anterior lobe – came from moutha.i.3 regions a.i.1.Pars distalis a.i.1.a.Major region of the region a.i.2.Pars intermedia a.i.3.Pars tuberalis a.i.4.True endocrine tissue a.i.5.Modified epithelial cells b.Posterior lobe – came from brain
