Receptors play a host of many vital roles in our bodies. In biochemistry, a protein molecule that receives and responds to a neurotransmitter, or other substance. Receptors are found in: nerve tissue, lung, liver, intestine, kidney, lymphatic tissue, and the spleen. In Cannabis, the CB1 and CB2 receptors play roles in our immune system and blood formation functions. Other processes they control include cognition, memory, anxiety, motor behavior, sensory, autonomic and neuroendocrine responses, glucose metabolism and insulin resistance, inflammatory effects, control of the vomiting reflex, nausea, hunger, and appetite control.
Receptors are also responsible for the pleasure we get from exercise, commonly known as the “runner’s high”, and are believed to be caused by Endorphins.
