Derived from fatty acids, particularly arachidonic acid, which is a component of cell membranes, prostaglandins constitute a group of lipid compounds. These bioactive molecules function as local signaling mediators, exerting a wide range of effects on various physiological processes in the body. By being produced and acting locally at the …
Serotonin (5-HT): Physiological Role, Clinical Implications
5-Hydroxytryptamine, commonly known as serotonin or 5-HT, is a monoamine neurotransmitter and a derivative of the amino acid tryptophan. It plays a crucial role in the central nervous system and various physiological processes, contributing to mood regulation, sleep-wake cycles, appetite control, and gastrointestinal function. Physiological Role of 5-Hydroxytryptamine (5-HT or …
Histamine: Physiological Role, Clinical Applications
Histamine is a biogenic amine, a compound derived from amino acids, that serves as a signaling molecule and neurotransmitter in the body. It is produced and stored in various cells, particularly mast cells and basophils, which are immune system components. When released, histamine plays a key role in several physiological …
Autocoids
Autocoids, short for “autonomous mediators,” refer to a diverse group of naturally occurring substances within the body that act locally to regulate physiological functions. These substances are produced in small quantities and exert their effects near the site of synthesis. Autocoids play essential roles in maintaining homeostasis and mediating various …
