The pituitary gland controls the activities of many other endocrine glands and hormone-producing cells around the body. The pituitary gland has two parts, the anterior and posterior lobes, which are under the control of a part of the brain known as the hypothalamus. The hypothalamus secretes releasing hormones that pass through the circulation to the pituitary’s anterior lobe, where they trigger the production of hormones that control other glands. Nerve cells in the hypothalamus secrete two hormones that pass down nerve fibres to be stored in the posterior lobe until they are needed.
