Transfer of neuroregulators from hypothalamic neurones to the pituitary blood supply takes place in an anatomically specialised region of the ventral hypothalamus known as the median eminence or tuberoinfundibular region (Fig. 1.2). Neurones that project to this region are called tuberoinfundibular neurones. These terminate in proximity to capillary walls within the median eminence, which drain into a venous system that in turn, supplies the sinusoids of the pituitary. By analogy with the venous supply of the liver, this vascular system is referred to as the hypophysial-portal system.
