Adrenaline of epinephrine can be seen in autonomic neuropathy or following adrenalectomy. Failure of the adrenal cortex, as with Addisons disease, can suppress epinephrine secretion as the activity of the synthesing enzyme, phenylethanolamine-"N"-methyltransferase, depends on the high concentration of cortisol that drains from the cortex to the medulla. In 1901, Jokichi Takamine patented a purified extract from the adrenal glands, and called it "adrenalin" (from the Latin for "on top of the kidneys" ("ad" and "renal"), which was trademarked by Parke, Davis & Co in the US. The British Approved Name and European Pharmacopoeia term for this drug is hence "adrenaline".
Central nervous system capabilities of the brain. Connecting each of the hemispheres is the corpus callosum as well as several additional commissures. One of the most important parts of the cerebral hemispheres is the cortex, made up of gray matter covering the surface of the brain. Functionally, the cerebral cortex is involved in planning and carrying out of everyday tasks. The hippocampus is involved in storage of memories, the amygdala plays a role in perception and communication of emotion, while the basal ganglia play a major role in the coordination of voluntary movement. This differentiates the central nervous system from the peripheral nervous
