Oxytocin and Anti diuretic Hormone (ADH)

Posterior Lob of Pituitary Gland

The hypothalamus a small region of the brain and coordination center of the endocrine system; it receives and integrates messages from the central nervous system. In response to these messages, the hypothalamus produces regulatory hormones (releasing factors) that pass directly to the nearby pituitary gland (Hypophysis), through special blood vessels and neurons that connect the two glands. The pituitary gland has two functionally distinct parts.

1-Posterior Lobe of Pituitary Gland (Neurohypophysis):             

This part contains the axonal endings of many neurons, originate from hypothalamus. These neurons produce the short peptide hormones oxytocin and vasopressin, which move down the axon to the nerve endings in the pituitary, where they are stored in secretory granules to await the signal for their release.
