Artificial organ a stationary power supply or other stationary resources such as filters or chemical processing units. (Periodic rapid recharging of batteries, refilling of chemicals, and/or cleaning/replacing of filters would exclude a device from being called an artificial organ.) Thus, a dialysis machine, while a very successful and critically important life support device that almost completely replaces the duties of a kidney, is not an artificial organ. Constructing and installing artificial organs, an extremely research-intensive and expensive process initially, may entail many years of ongoing maintenance services not needed by a natural organ.: The use of any artificial organ by humans is
Cerebellar degeneration cerebellar damage on a temporary or permanent basis, but can also affect other tissues of the central nervous system, those including the cerebral cortex, spinal cord and the brainstem (made up of the medulla oblongata, midbrain, and pons). Cerebellar degeneration can be attributed to a plethora of hereditary and non-hereditary conditions. More commonly, cerebellar degeneration can also be classified according to conditions that an individual may acquire during their lifetime, including infectious, metabolic, autoimmune, paraneoplastic, nutritional or toxic triggers. Patients suffering from cerebellar degeneration experience a progressive loss of nerve cells (Purkinje cells) throughout the cerebellum. As well as this,
