• Sagittal section of a human pituitary, showing the relationship of its blood supply to the hypothalamic neurosecretory cells in the adenohypophysis. Neurosecretory neurons are shown secreting releasing factors into the capillary networks giving rise the long and short hypophyseal portal vessels, respectively. The releasing hormones reach the hormone-secreting cells of the anterior lobe via the portal vessels.
