What is your pitutary?The pituitary is a small but extremely important gland in the body. It's often referred to as the 'master gland'.The pituitary gland lies outside the dura and It rests in the sella turcica (a small depression at the base of the skull) below the optic chiasm. It is connected to the hypothalamus by the pituitary stalk and is divided into 2 portions, the anterior and posterior lobes. The hypothalamus actively senses the external and internal environment and directly communicates by producing hormones which are stored in the posterior lobe of the pituitary gland and later released and with the anterior lobe, by sending signals to release hormones made by the anterior lobe. These hormones are small molecular messengers that that allow different organs in the body to communicate with each other. The pituitary lies almost directly behind the area between the eyes and can be accessed surgically through the back of the nose.

What does it do?
 The pituitary gland releases hormones that influence most systems in the body. These hormones  directly affect the functions of the thyroid gland, the adrenal gland, and the gonads, as well as directing growth, milk production, and water balance.
