Thermal Regulation: Function, Tasks, Role & Diseases

Thermoregulation refers to all the regulatory processes involved in maintaining body temperature. Warm-blooded animals maintain a constant temperature, regardless of outside temperatures. The center of thermoregulation is the hypothalamus. What is thermoregulation? Thermoregulation refers to all the regulatory processes involved in maintaining body temperature. Warm-blooded animals must maintain their body temperature because the various systems … Thermal Regulation: Function, Tasks, Role & Diseases

Short Feedback Mechanism: Function, Tasks, Role & Diseases

The term short-feedback mechanism originates from endocrinology. It refers to a regulatory circuit in which a hormone can directly inhibit its own action. What is the short-feedback mechanism? Short-feedback mechanisms are independent, very small control circuits. One example is the short-feedback mechanism of thyroid-stimulating hormone (TSH). The short-feedback mechanism is one of the regulatory circuits. … Short Feedback Mechanism: Function, Tasks, Role & Diseases

Paracrine Secretion: Function, Role & Diseases

Paracrine secretion is the medical term for hormone secretion into the interstitium that acts on cells in the immediate environment. Paracrine secretion primarily serves to differentiate tissues. Paracrine disorders can affect bone formation, for example, and show effects on the entire hormonal system. What is paracrine secretion? Paracrine secretion is the medical term for hormone … Paracrine Secretion: Function, Role & Diseases

Neurohypophysis: Structure, Function & Diseases

Like the adenohypophysis, the neurohypophysis is a part of the pituitary gland (hypophysis). However, it is not a gland itself but a component of the brain. Its role is to store and provide two important hormones. What is the neurohypophysis? The neurohypophysis (posterior pituitary) is the smaller component of the pituitary gland, along with the … Neurohypophysis: Structure, Function & Diseases

Pituitary Gland: Structure, Function & Diseases

The pituitary gland, in German Hirnanhangsdrüse, is a hormonal gland about the size of a hazelnut seed, located at the level of the nose and ears in the middle cranial fossa. It works closely with the hypothalamus and, like an interface between the brain and bodily processes, controls the release of vital hormones that influence … Pituitary Gland: Structure, Function & Diseases

Adenohypophysis: Structure, Function & Diseases

As part of the pituitary gland, the adenohypophysis is an important endocrine gland. It is responsible for producing a number of different hormones. Disorders in the function of the adenohypophysis lead to typical diseases caused by a deficiency or excess of certain hormones. What is the adenohypophysis? The adenohypophysis is called the anterior pituitary gland … Adenohypophysis: Structure, Function & Diseases

Pituitary Gland Inflammation: Causes, Symptoms & Treatment

Hypophysitis is a rarely occurring inflammation of the pituitary gland. Various forms of pituitary inflammation are known, but not all physiologic and immunologic relationships have been elucidated, especially in lymphocytic pituitary inflammation, which is probably due to an autoimmune response of the body. As it progresses, pituitary inflammation leads to progressive loss of pituitary function, … Pituitary Gland Inflammation: Causes, Symptoms & Treatment

Milk Ejection Reflex: Function, Tasks, Role & Diseases

The milk ejection reflex is a lactation reflex triggered by the infant sucking on the maternal breast. The registered touch causes milk to shoot into the breast. Disorders of the reflex are either due to a deficiency of the hormone involved, oxytocin, or are associated with neurologic disorders. What is the milk ejection reflex? The … Milk Ejection Reflex: Function, Tasks, Role & Diseases

Endocrine System: Structure, Function & Diseases

As a complex system, the hormone system controls the coordination of the functions of all organs of the organism. In humans, over thirty different hormones (messenger substances) are responsible for this. The medical specialty of endocrinology deals with the disorders within the endocrine system. What is the endocrine system? The endocrine system includes both endocrine … Endocrine System: Structure, Function & Diseases

Long-feedback Mechanism: Function, Tasks, Role & Diseases

The long-feedback mechanism is a principle of feedback as it is relevant to hormone balance in the human body. Among the best-known long-feedback mechanisms is the regulatory loop between thyroid hormones and TSH (thyrotropin). Disturbances within this control loop occur in Graves’ disease, among others. What is the long-feedback mechanism? Among the best-known long-feedback mechanisms … Long-feedback Mechanism: Function, Tasks, Role & Diseases

Proopiomelanocortin: Function & Diseases

Proopiomelanocortin (POMC) is a so-called prohormone from which over ten different active hormones can be formed. The prohormone is synthesized in the adenohypophysis, hypothalamus, and placenta and epithelia to express the corresponding hormones. Deficiency of POMC leads to severe hormonal imbalances in the organism. What is proopiomelanocortin? Proopiomelanocortin is a protein composed of 241 different … Proopiomelanocortin: Function & Diseases

Galactogenesis: Function, Tasks, Role & Diseases

Galactogenesis is the infusion of milk into the mammary gland ducts that occurs during the postpartum period after pregnancy. Galactogenesis is a condition of lactation reflexes. Unlike lactation disorders, disorders of galactogenesis are not due to faulty breastfeeding but are usually due to excess placental steroid hormones. What is galactogenesis? Galactogenesis refers to the infusion … Galactogenesis: Function, Tasks, Role & Diseases
