Describe the functions of the spinal cord correct answers Sensory processor- receives info from entire body (except head)- sends info to cerebrum, brain stem, cerebellum, other regions. Motor outflow- lower motor neurons travel through ventral horns (final common pathway-essential for movement), upper motor neurons in white matter (descending from bran). Reflexes - local circuits. A reflex is a stereotyped movement driven by a sensory stimulus. "The spinal cord is anatomically segmented...
