The hypothalamic–pituitary–thyroid axis (HPT axis for short, a.k.a. thyroid homeostasis or thyrotropic feedback control) is part of the neuroendocrine system responsible for the regulation of metabolism and also responds to stress. As its name suggests, it depends upon the hypothalamus, the pituitary gland, and the thyroid gland.
The hypothalamic–pituitary–adrenal axis (HPA axis or HTPA axis) is a complex set of direct influences and feedback interactions among three components: the hypothalamus (a part of the brain located below the thalamus), the pituitary gland (a pea-shaped structure located below the hypothalamus), and the adrenal (also called "suprarenal ...
Hypothalamic disease is a disorder presenting primarily in the hypothalamus, which may be caused by damage resulting from malnutrition, including anorexia and bulimia eating disorders, [1] [2] genetic disorders, radiation, surgery, head trauma, [3] lesion, [1] tumour or other physical injury to the hypothalamus. The hypothalamus is the control ...
Certain metabolic disorders, such as hemochromatosis (extra iron buildup in the body), can cause or contribute to testosterone deficiency by affecting pituitary or hypothalamic function. Alcohol ...
The hypothalamus has a central neuroendocrine function, most notably by its control of the anterior pituitary, which in turn regulates various endocrine glands and organs. Releasing hormones (also called releasing factors) are produced in hypothalamic nuclei then transported along axons to either the median eminence or the posterior pituitary ...
It is possible for the function of these hormones to be altered by physical activity. [2] In posterior pituitary we have hormones that control absorption of water and oxytocin. Anterior hypophysis, neurosecretory cells which release hormones. There is a pituitary portal system, with which the hormones are transported.
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. [1] [2] If there is decreased secretion of one specific pituitary hormone, the condition is known as selective hypopituitarism. [3]
Some other symptoms of anemia include problems concentrating, dizziness, chest pain, an abnormally rapid heart rate, shortness of breath, and pale skin. ... Pituitary gland or hypothalamus tumors ...
