By this method, body diagrams can be derived by pasting organs into one of the "plain" body images shown below. This method requires a graphics editor that can handle transparent images, in order to avoid white squares around the organs when pasting onto the body image. Pictures of organs are found on the project's main page. These were ...
3D model of 2-Arachidonoylglycerol, an endocannaboid. The endocannabinoid system (ECS) is a biological system composed of endocannabinoids, which are neurotransmitters that bind to cannabinoid receptors, and cannabinoid receptor proteins that are expressed throughout the central nervous system (including the brain) and peripheral nervous system.
The short-term effects of cannabis are caused by many chemical compounds in the cannabis plant, including 113 [clarification needed] different cannabinoids, such as tetrahydrocannabinol, and 120 terpenes, [1] which allow its drug to have various psychological and physiological effects on the human body.
Marijuana's official designation as a Schedule 1 drug — something with "no accepted medical use" — means it is pretty tough to study.. Yet both a growing body of research and numerous ...
CB1 receptors are expressed most densely in the central nervous system and are largely responsible for mediating the effects of cannabinoid binding in the brain. Endocannabinoids released by a depolarized neuron bind to CB1 receptors on pre-synaptic glutamatergic and GABAergic neurons, resulting in a respective decrease in either glutamate or ...
Researchers in Italy and the U.K. have found high-potency marijuana can affect the corpus callosum, the nerves that connect the halves of the brain. 'Skunk' marijuana may hinder brain's ability to ...
There has been significant advancement in understanding the structural changes that occur in parts of the brain involved in the reward pathway (mesolimbic system) that underlies addiction. [3] Most research has focused on two portions of the brain: the ventral tegmental area, (VTA) and the nucleus accumbens (NAc). [4]
There are two known subtypes of cannabinoid receptors, termed CB 1 and CB 2. [6] [7] The CB 1 receptor is expressed mainly in the brain (central nervous system or "CNS"), but also in the lungs, liver and kidneys. The CB 2 receptor is expressed mainly in the immune system, in hematopoietic cells, [8] and in parts of the brain. [9]
