Hypothalamus The hypothalamus (from Greek ὑπό, under and θάλαμος, thalamus) is a portion of the brain that contains a number of small nuclei with a variety of functions. One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland (hypophysis).

Hypopituitary Hypopituitary Overview. Hypopituitarism is a condition in which the pituitary gland (a small gland at the base of the brain) does not produce one or more of its hormones or not enough of them.his condition may occur because of disease in the pituitary or hypothalamus (a part of the brain that contains hormones that control the pituitary gland). When there is low or no production of all the pituitary hormones, the condition is called panhypopituitarism. This condition may affect either children or adults.

Functional Anatomy of the Hypothalamus and Pituitary Gland The pituitary gland, also known as the hypophysis, is a roundish organ that lies immediately beneath the hypothalamus, resting in a depression of the base of the skull called the sella turcica (Turkish saddle). In an adult human or sheep, the pituitary is roughly the size and shape of a garbonzo bean.

- The pituitary gland or hypophysis is a small gland about 1 centimeter in diameter or the size of a pea. It is nearly surrounded by bone as it rests in the sella turcica, a depression in the sphenoid bone. The gland is connected to the hypothalamus of the brain by a slender stalk called the infundibulum.

- Hypothalamus. The hypothalamus is a section of the brain responsible for the production of many of the body’s essential hormones, chemical substances that help control different cells and organs.he hypothalamus' primary function is homeostasis, which is to maintain the body's status quo system-wide. Hypothalamic hormones include thyrotropin-releasing, gonadotropin-releasing, growth hormone-releasing, corticotrophin-releasing, somatostatin, and dopamine hormones.

Hypothalamus The hypothalamus is responsible for certain metabolic processes and other activities of the autonomic nervous system. It synthesizes and secretes certain neurohormones, often called releasing hormones or hypothalamic hormones, and these in turn stimulate or inhibit the secretion of pituitary hormones.ne of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland (hypophysis). The hypothalamus is located below the thalamus, just above the brainstem and is part of the limbic system.

- The hypothalamus is the portion of the brain responsible for sending signals to the pituitary gland, which, in turn, sends hormonal stimuli to the ovaries in the form of FSH and LH to initiate egg maturation. If the hypothalamus fails to trigger and control this process, immature eggs will result.

Hypopituitarism [edit on Wikidata] Hypopituitarism is the decreased (hypo) secretion of one or more of the eight hormones normally produced by the pituitary gland at the base of the brain. If there is decreased secretion of most pituitary hormones, the term panhypopituitarism (pan meaning all) is used.

- Panhypopituitarism Hypopituitarism is a medical term describing deficiency (hypo) of one or more hormones of the pituitary gland. The pituitary produces a number of important regulating hormones, and its function is mainly regulated by the hypothalamus.efinition. Hypopituitarism is loss of function in an endocrine gland due to failure of the pituitary gland to secrete hormones which stimulate that gland's function. The pituitary gland is located at the base of the brain.

What Is The Hypothalamus? The hypothalamus functions as a type of thermostat for the body. It sets a desired body temperature, and stimulates either heat production and retention to raise the blood temperature to a higher setting, or sweating and vasodilation to cool the blood to a lower temperature.

Neurocardiology The hypothalamus is the part of the brain that regulates function and responds to stress. When the brain perceives environmental danger, the amygdala fires a nerve impulse to the hypothalamus to initiate the body's fight-or-flight mode through the sympathetic nervous system.

- Definition. Hypothalamic dysfunction is a problem with part of the brain called the hypothalamus. The hypothalamus helps control the pituitary gland and regulates many body functions.he most common causes of hypothalamic dysfunction are surgery, trauma (injury), tumors, and radiation. Other causes include: 1  Anorexia nervosa or bulimia. 2  Bleeding. 3  Genetic disorders that cause iron buildup in the body. 4  Head trauma. 5  Infections and swelling (inflammation). 6  Malnutrition.

What is the function of the hypothalamus? The hypothalamus is a small area in the center of the brain that has many jobs. It plays an important role in hormone production and helps to stimulate many important processes in the body. When the hypothalamus is not working properly, it can cause problems in the body leading to many disorders.

An Overview of the Hypothalamus Hypothalamic Disease. A disease or disorder of the hypothalamus is known as a hypothalamic disease. A physical injury to the head that impacts the hypothalamus is one of the most common causes of hypothalamic disease.he hypothalamus is highly involved in pituitary gland function. When it receives a signal from the nervous system, the hypothalamus secretes substances known as neurohormones that start and stop the secretion of pituitary hormones.

Hypopituitarism Hypopituitarism is a disorder in which your body doesn’t make enough pituitary hormones. The pituitary gland is a small, bean-shaped gland at the base of your brain. It plays a role in controlling your body’s endocrine system, a group of glands that produce and secrete hormones to regulate your body’s processes.
