Answer:

Explanation:

The hypothalamus is a structure of the diencephalon of the brain located anterior and inferior to the thalamus (Figure 1). It has both neural and endocrine functions, producing and secreting many hormones. In addition, the hypothalamus is anatomically and functionally related to the pituitary gland (or hypophysis), a bean-sized organ suspended from it by a stem called the infundibulum (or pituitary stalk). The pituitary gland is cradled within the sellaturcica of the sphenoid bone of the skull. It consists of two lobes that arise from distinct parts of embryonic tissue: the posterior pituitary (neurohypophysis) is neural tissue, whereas the anterior pituitary (also known as the adenohypophysis) is glandular tissue that develops from the primitive digestive tract. The hormones secreted by the posterior and anterior pituitary, and the intermediate zone between the lobes are summarized in Table 3.

This illustration shows the hypothalamus-pituitary complex, which is located at the base of the brain and shown here from a lateral view. The hypothalamus lies inferior and anterior to the thalamus, which is sits atop the brainstem. The hypothalamus connects to the pituitary gland by the stalk-like infundibulum. The pituitary gland looks like a sac containing two balls hanging from the infundibulum. The “balls” are the anterior and posterior lobes of the pituitary. Each lobe secretes different hormones in response to signals from the hypothalamus.
