Paraplegia quite challenging at first for those with a spinal cord injury (SCI). With the aid of physiotherapists and occupational therapists, individuals with an SCI can learn new skills and adapt previous ones to maximize independence, often living independently within the community. Olfactory ensheathing cells (OEC) have been transplanted with success into the spinal cord of Polish man named Darek Fidyka, who was the victim of a knife attack that left him paraplegic in 2010. In 2014, Fidyka underwent pioneering spinal surgery that used nerve grafts, from his ankle, to 'bridge the gap' in his severed spinal cord and OEC's to
Motor nerve cord ipsilaterally, on the same side, and exit the spinal cord at the ventral horn of the spinal cord on either side. Motor nerves communicate with the muscle cells they innervate through motor neurons once they exit the spinal cord. Motor nerves can vary based on the subtype of motor neuron they are associate with. Alpha motor neurons target extrafusal muscle fibers. The motor nerves associated with these neurons innervate extrafusal skeletal muscle fibers and are responsible for muscle contraction. These nerve fibers have the largest diameter of the motor neurons and require the highest conduction velocity of the three
