In the spinal cord are two areas termed "enlargements" one in the cervical cord, one in the lumbar cord. Why are these areas enlarged? they contain neurons and axons that serve the limbs they are swollen because they are easily damaged the areas have more myelin neurons axons and glia in those areas are bigger

Watch this video (http://openstaxcollege.org/I) graymatter) to learn about the gray matter of the spinal cord that receives input from fibers of the dorsal (posterior) root and sends information out through the fibers of the ventral (anterior) root. As discussed in this video, these connections represent the interactions of the CNS with peripheral structures for both sensory and motor functions. The cervical and lumbar spinal cords have enlargements as a result of larger populations of neurons. What are these enlargements responsible for?
