NettetSpinal cord reflexes are simple behaviors produced by central nervous system (CNS) pathways that lie entirely within the spinal cord. The sensory afferent fibers that evoke these reflexes enter the spinal cord and activate spinal motor neurons directly or through a chain of one or more spinal interneurons. Although these pathways are entirely ...

Due to the extensive range covered by the somatic nervous system, these conditions can either localize to a region of the body or can be widespread and generalized. Some of these …
NettetMost sensory and motor pathways in the central nervous system cross the midline. Comparing between different neuronal pathways in different species suggest that, fibers crossing is most probably a response to the development of separated parts for the body during the process of evolution.
