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.
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. Download here; Click
