the spinal cord and the influence of its damage on
... In spinal cord injury, the destruction of nerve fibres that carry motor signals from the brain to the torso and limbs leads to muscle paralysis. Destruction of sensory nerve fibres can lead to loss of sensations such as touch, pressure and temperature. Largely unknown is that the spinal cord control ...
