Neuroendocrinology its product?" and "how is information encoded in electrical activity?"[It appears that this is a primary source observation.] The pituitary gland is divided into two sections: the anterior pituitary and the posterior pituitary. The hypothalamus controls the anterior pituitary's hormone secretion by sending trophic hormones down the hypothalamohypophysial portal system. For example, thyrotropin-releasing hormone stimulates the secretion of thyroid-stimulating hormone by the anterior pituitary. The posterior pituitary is innervated by the hypothalamus; the hormones oxytocin and vasopressin are synthesized by neuroendocrine cells in the hypothalamus and stored at the nerves' ends in the posterior pituitary. They are secreted directly into
Pituitary pars intermedia dysfunction Pituitary pars intermedia dysfunction Pituitary pars intermedia dysfunction (PPID), or equine Cushing's disease, is an endocrine disease affecting the pituitary gland of horses. It is most commonly seen in older animals, and is classically associated with the formation of a long, wavy coat (hirsutism) and chronic laminitis. Unlike the human and canine forms of Cushing's disease, which most commonly affect the pars distalis region of the pituitary gland, equine Cushing's disease is a result of hyperplasia or adenoma formation in the pars intermedia. This adenoma then secretes excessive amounts of normal products, leading to clinical signs. The pituitary gland consists
