Document Summary

Blood supply is unique for the anterior and posterior pituitary. 2 bundles of nerves produce neural hormones that then store it in posterior. Part of the brain as an extension of the hypothalamus. The cell bodies are in the hypothalamus and the axons are in the tract. Hypothalamus --> produces a hormone ---> transported down axon --> axon terminal --> waits for signal to get distributed through vascular bed. The cell bodies are located in the nuclei and their axons travel through the infundibulum. As long as baby continues to suckle the milk will be produced. Rathke"s pound = from the oral mucosa extends up and eventually becomes the ap. With time the connection disappears, therefore the ap becomes attached to pp. Other than the tissue connection, there is no tract connecting them. Ap is true and pure endocrine gland. Control of hormones is done by hypothalamus. Made up by superior hypophyseal artery and superior hypophyseal veins.
