H RECEPTORS Meaning and
Definition
-
H receptors are a type of histamine receptor found in the body that play a crucial role in various physiological processes. Histamine is a chemical messenger that is released by cells in response to injury, allergens, or other stimuli, and it produces a wide range of effects in the body through its interactions with different histamine receptor subtypes.
H receptors are classified into two main subclasses: H1 and H2 receptors. H1 receptors are predominantly found in smooth muscles, endothelial cells, and nerve cells, and their activation leads to effects such as increased vasodilation, increased vessel permeability, smooth muscle contraction, itching, and pain. H1 receptor antagonists are commonly used medications to alleviate allergic reactions and treat conditions like allergies, hay fever, and hives.
On the other hand, H2 receptors are mainly located in the stomach lining, where their activation stimulates the production of gastric acid by parietal cells. H2 receptor antagonists, also known as H2 blockers, are widely used in the treatment of conditions like peptic ulcers, gastroesophageal reflux disease (GERD), and excessive stomach acid production.
H receptors are crucial mediators of various physiological responses and are potential targets for therapeutic interventions in conditions related to allergy, inflammation, and gastric acid regulation. Understanding the function and regulation of H receptors is essential for the development of effective medications to treat a wide range of disorders.

Etymology of H RECEPTORS
The word "H receptors" is an abbreviation for "histamine receptors". The etymology of the term "histamine" dates back to its discovery by Sir Henry Dale in 1910. The name "histamine" is derived from the Greek words "histos" meaning tissue, and "amine", indicating its chemical structure as an amine compound. Thus, "histamine receptors" or "H receptors" refer to the receptors that bind and respond to histamine, a compound involved in various physiological processes in the body.
