Organization of the Spinal Cord
The Spinal Cord
Sensory information from the body is transmitted into the central nervous system (CNS) through the dorsal root projections into the spinal cord. Motor neurons in the spinal cord project their axons into the periphery to innervate muscles and autonomic ganglia. Somatic perceptions, coordinated movements, and autonomic functions depend on the integrity of the spinal cord and its projections. The neurons and fiber bundles within the spinal cord are organized in a simpler and more uniform way than other parts of the CNS.
