In addition to the varied and important functions performedby the cord as a system of reflex centers controlling the activitiesof numerous glands and visceral organs as well as the so-calledvoluntary muscles, it is physiologically most important as a path-way to and from the brain. All the fibers, numbering more thanhalf a million, that enter the cord through the posterior roots ofthe spinal nerves bring in afferent impulses, which may be continuedupward by definite tracts that end eventually in the cortex of thecerebrum, the cerebellum, or some other portion of the brain. Onthe other hand, many of the efferent impulses originating re
