Loss of nerve supply.
* * *
n.
interruption of the nerve supply to the muscles and skin. The muscle is paralysed and its normal tone (elasticity) is lost. The muscle fibres shrink and are replaced by fat. A denervated area of skin loses all forms of sensation and its subsequent ability to heal and renew its tissues may be impaired.
