Overview of the Posterior Pituitary [Neurohypophysis]

The video explains the roles of the hypothalamus and pituitary glands in hormone regulation. It distinguishes between the anterior and posterior pituitary, highlighting the anterior's reliance on releasing hormones and the posterior's direct hormone release via neurons. The posterior pituitary, or neurohypophysis, is neural tissue and not a true gland. It stores and releases oxytocin and ADH, which are produced in the hypothalamus. Oxytocin aids in milk ejection and uterine contractions, while ADH regulates water retention and vasoconstriction. Both hormones also play roles in pair bonding.
