Document Summary
Posterior pituitary: actually and extension of neurons of the paraventricular and supraoptic nuclei of the hypothalamus, cell bodies in this region rest in hypothalamus, axons descend as hypothalamic. Hypophyseal tract within infundibulum: ends in axon terminals that comprise the posterior pituitary, this gland does not produce hormones, stores and secretes hormones that are produced by the hypothalamus, paraventricular nuclei. Produces hormone oxytocin: supraoptic nuclei . Adh: hormones travel along the axons into storage sites in the axon terminals of posterior, due to signals from same hypothalamic neurons hormones are released from axon terminals into the bloodstream. In both males and females: oxytocin involved in feelings of love, closeness and sexual response, solute concentration or blood osmolarity. Thyroid-stimulating hormone (tsh: caused by thyrotropin-releasing hormone (trh) from hypothalamus, triggers secretion of thyroid hormones by thyroid gland, classic negative feedback loop, elevated levels of thyroid hormones in blood trigger drop in production of trh.
