Pituitäres

"Pituitäres" is a term derived from the German word "Pituitary," referring to the pituitary gland, a small but vital endocrine gland located at the base of the brain within the sella turcica. The pituitary gland is often termed the "master gland" because it regulates a broad range of hormonal functions that influence growth, metabolism, reproduction, and stress response.

The gland is divided into two main parts: the anterior pituitary (adenohypophysis) and the posterior pituitary (neurohypophysis). The anterior pituitary secretes hormones such as growth hormone (GH), adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), prolactin, and gonadotropins (LH and FSH). These hormones control various target organs and physiological processes. The posterior pituitary stores and releases hormones produced by the hypothalamus, including vasopressin (antidiuretic hormone) and oxytocin.

Disorders related to the pituitary gland are common and can lead to hormonal imbalances. Pituitary tumors, known as adenomas, are among the most frequent issues and can cause excess hormone production or deficiency. These tumors may lead to conditions such as acromegaly, characterized by excess growth hormone, or hypopituitarism, which results from hormone deficiencies.

Diagnosis of pituitary disorders involves imaging techniques like MRI, alongside blood and urine tests to assess hormonal levels. Treatment options include medical therapy, surgical removal of tumors, and radiation therapy, depending on the specific condition.

Overall, the pituitary gland plays a central role in endocrine regulation, affecting multiple body systems and maintaining hormonal balance essential for health and homeostasis.
