Inflammation is regulated by a complex network of chemical mediators that orchestrate the response to injury or infection. These mediators originate from various cells and tissues and include vasoactive amines, lipid mediators, cytokines, chemokines, and other small molecules. They play roles in vasodilation, increased vascular permeability, leukocyte recruitment, and other aspects of the inflammatory response. … Read more
5-HT, or serotonin, is a vital neurotransmitter with a broad range of physiological functions, influencing mood, appetite, sleep, and other behaviors. It also plays roles in the gastrointestinal system, cardiovascular system, and hemostasis. The significance of serotonin extends from its influence on mental health to its involvement in various bodily functions. This note provides a … Read more
Serotonin, also known as 5-hydroxytryptamine (5-HT), is a monoamine neurotransmitter and neuromodulator that plays crucial roles in regulating mood, emotion, cognition, sleep, appetite, and various physiological processes in the central nervous system (CNS) and peripheral tissues. Serotonin is synthesized from the amino acid tryptophan and is widely distributed throughout the body, with the majority of … Read more
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 Serotonin) 1. Neurotransmission: – … Read more
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 physiological processes. Examples of autocoids … Read more
Neurotransmitters are chemical messengers that play a crucial role in transmitting signals across synapses in the nervous system. These signaling molecules transmit information from one neuron to another or from neurons to target cells (e.g., muscles or glands). Neurotransmitters can be classified based on various criteria, and each type has specific properties. Here’s a classification … Read more
