[← Back to the Technical Info Summary Hub](https://cedclinic.com/topic-technical-info/)Diagram & referenceA visual reference. The evidence, sources and clinical interpretation are in the linked article.About this diagramA one page infographic of the [endocannabinoid system](https://cedclinic.com/cbd-gummies-diabetes-management-evidence-safety/). The center is a full body figure with dots placed on organs and tissues, and a key at the right says which dot means CB1, which means CB2 and which means both, with labels running out to the brain, eye, tonsils, thyroid, upper airway, thymus, heart, liver, spleen, stomach, bones, skin, ovaries, uterus, prostate and testes, plus a brain inset for cortex and cerebellum. The left panel draws receptors on a neuron and where plant cannabinoids bind, and the lower strip gives the chemical structures of anandamide and 2-arachidonoylglycerol.The evidence behind it[Read the evidence: a working map of CB1 and CB2 distribution drawn from the original cloning and autoradiography studies](https://cedclinic.com/cb1-and-cb2-receptor-distribution-in-the-body/)That article carries the cited studies, the limits of the evidence, and the clinical interpretation.
