The Endocannabinoid System: Unraveling the Complex Web of Regulation in Human Physiology

The endocannabinoid system (ECS) is a fascinating and intricate network of receptors, endocannabinoids, and enzymes that play a crucial role in regulating various physiological processes in the human body. This paper provides an in-depth exploration of the ECS, including its discovery, components, functions, and therapeutic implications. The review aims to shed light on the profound impact of the ECS on human health and how it serves as a potential target for therapeutic interventions.

The discovery of the endocannabinoid system in the late 20th century revolutionized our understanding of human physiology. This section provides a historical overview of the ECS, from the identification of cannabinoids to the isolation of endocannabinoids and the subsequent revelation of a complex regulatory system within the human body.

Components of the Endocannabinoid System

An exploration of the key components of the ECS, including cannabinoid receptors (CB1 and CB2), endocannabinoids (anandamide and 2-arachidonoylglycerol), and enzymes responsible for their synthesis and degradation (FAAH and MAGL). Understanding these components is crucial for unraveling the intricate signaling mechanisms orchestrated by the ECS.
