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
Segmentation in the human nervous system central nervous system (CNS). Along with the brain, it develops from the dorsal nerve cord in the embryonic stage. The spinal cord consists of such segmental enlargements called ganglia. These ganglia form the basis for the peripheral nervous system’s (PNS) sensory and motor neurons that innervate various parts of the body. The vertebral segmentation is a process that forms a distinctive feature of the group. At first, somites form as a spherical epithelial structure with a central lumen lined by radially arranged cells. Structures such as mesenchymal sclerotome which later develop as the vertebral column along with notochord, and dermomyotome
