Summary Introduction
Introduction:
There are clusters of specialized cells present in the hypothalamus which are known as neurosecretory cells. Thin fibers or axons are grown by neurosecretory cells which end in capillary bed and connect hypothalamus to anterior lobe of the pituitary. The neurosecretory cells produce six different regulatory hormones which can be either releasing or inhibiting hormones.
