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".
Autonomic networking the key challenges to be solved by effective security. The security sub-system interoperates directly with: The connection fabric supports the interaction with all the elements and sub-systems of the autonomic system. It may be composed of a variety of means and mechanisms, or may be a single central framework. The biological equivalent is the central nervous system itself – although referred to as the autonomic system, it actually is only the communication conduit between the human body’s faculties. Consequently, it is currently under research by many research projects, how principles and paradigms of mother nature might be applied to networking.
