Posterior pituitary neurosecretory cells extending from the supraoptic and paraventricular nuclei of the hypothalamus. These axons store and release neurohypophysial hormones oxytocin and vasopressin into the neurohypophyseal capillaries, from there they get into the systemic circulation (and partly back into the hypophyseal portal system). In addition to axons, the posterior pituitary also contains pituicytes, specialized glial cells resembling astrocytes assisting in the storage and release of the hormones. Classification of the posterior pituitary varies, but most sources include the two regions below: The median eminence is only occasionally included as part of the posterior pituitary. Other sources specifically exclude it from the
Combined rapid anterior pituitary evaluation panel by TRH and rises in luteinizing hormone (LH) and follicle-stimulating hormone (FSH) caused by GnRH. Blood glucose levels are also monitored to ensure appropriate levels of hypoglycemia are achieved. The triple bolus test was introduced in 1973 by physicians from the London Royal Postgraduate Medical School and Queen Elizabeth Hospital, Birmingham. It followed earlier reports combining insulin and vasopressin analogues in the diagnosis of hypopituitarism. Combined rapid anterior pituitary evaluation panel A triple bolus test or a dynamic pituitary function test is a medical diagnostic procedure used to assess a patient's pituitary function. A triple bolus test is usually ordered
