Explain how the hypothalamus controls the release of hormone

Explain how the hypothalamus controls the release of hormones from the posterior and anterior pituitary.

Solution

The pituitary gland is called the master gland which controls the relase of hormones of all other endocrine glands. Pituitary gland is in turn controlled by the Hypothalamus. Pituitary gland has two comonents. Anterior and Posterior pituitary gland. Pituitary is connceted as a stalk to the hypothalamus. Hypothalamus controls the anterior pituitary via the parvocellular neurons and posterior pituitry via the magnocellular neurons. They are also connceted by blood vessels. The anterior pituitary receives signals from the hypothalamus in the form of hypothalamic releasing hormones which regulates the release of hormones of the anterior pituitary and which inturn regulate other endocrine gland secretions. The posterior pituitary cannot produce any hormones by itself. It just stores the hormones released by the hypothalamus and releases when required.
