releasing hormone

The scientist studies the releasing hormone in a laboratory setting.

Definition

Noun: 1. A hormone produced in the hypothalamus: Any of several hormones produced in the hypothalamus of the brain. These hormones are transported to the anterior pituitary gland, where they specifically stimulate or inhibit the release of other pituitary hormones. 2. A regulatory neurohormone: A substance that acts as a chemical messenger from the brain to control the endocrine system by triggering the secretion of specific hormones from the anterior pituitary.

Examples of Usage
  • The releasing hormone known as corticotropin-releasing hormone (CRH) signals the pituitary to release adrenocorticotropic hormone (ACTH).
  • Scientists studied the effect of the growth hormone-releasing hormone (GHRH) on development.
  • The hypothalamus secretes a gonadotropin-releasing hormone (GnRH) to regulate reproduction.
Advanced Usage
  • In medical therapy: Synthetic versions of certain releasing hormones, like gonadotropin-releasing hormone (GnRH), are used in treatments for conditions such as infertility or hormone-sensitive cancers.
    • The patient was given a GnRH agonist to regulate hormone levels.
  • In diagnostic testing: Releasing hormones can be administered in tests to assess the functional capacity of the pituitary gland.
    • A growth hormone-releasing hormone stimulation test was performed.
Variants and Related Words
  • Releasing Factor: A synonym for releasing hormone, often used interchangeably in scientific literature.
  • Hypophysiotropic Hormone: A more technical term emphasizing the hormone's target (the pituitary gland, or hypophysis).
  • Stimulating Hormone: Note: This is a related but distinct concept. A (e.g., thyroid-stimulating hormone, TSH) is typically released the pituitary in response to a from the hypothalamus.
  • Inhibiting Hormone: Some hypothalamic hormones, like somatostatin (growth hormone-inhibiting hormone), function to the release of pituitary hormones.
Synonyms
  • Releasing Factor
  • Hypothalamic Releasing Hormone
  • Hypophysiotropic Hormone
Related Phrases and Compounds
  • Hypothalamic-Pituitary Axis: The critical functional connection between the hypothalamus (which produces releasing hormones) and the pituitary gland.
  • [Specific Name]-Releasing Hormone (XRH): The standard naming convention, where "X" denotes the target pituitary hormone (e.g., Thyrotropin-Releasing Hormone, TRH; Gonadotropin-Releasing Hormone, GnRH).
releasing hormone

The scientist studies the releasing hormone in a laboratory setting.

Noun
  1. any of several hormones produced in the hypothalamus and carried by a vein to the anterior pituitary gland where they stimulate the release of anterior pituitary hormones; each of these hormones causes the anterior pituitary to secrete a specific hormone
  2. a substance produced by the hypothalamus that is capable of accelerating the secretion of a given hormone by the anterior pituitary gland
