    81. Effects of injury.—Injury to nerves causes loss of power or sensation ‘in the parts which they supply. The nourishment of the paralysed part also suffers. Pressure sores are especially likely to appear within an area of sensory loss. The spinal cord is composed of large nerve cells, and nerve fibres connecting the brain with the trunk and limbs. When it is torn through or badly crushed, the result is paralysis of both sides of the body below the point of injury, and loss of sensation, with paralysis of bladder and bowel. The spinal cord if divided does not recover. When a nerve is completely severed, it may be repaired, but. this takes a long time, and sensation and motor power return very slowly.
