Pituitary and hypothalamic physiology.

Professor P. M. Daniel has described in the first paper the nervous pathways connecting the hypothalamus to the posterior pituitary and how the posterior pituitary merely stores the hormones vasopressin, oxytocin (which has no clearly defined function in man), and neurophysin, the large molecule or molecules which bind the other hormones. For many years the anterior pituitary was thought to be very different but recently it has been realised that conceptually it is quite similar.
