Is the lateral horn sensory or motor
WitrynaThe ventral horn contains the cell bodies of motor neurons that send their axons out via the ventral roots to terminate on striated muscles. Thus, one important general rule of organization is that neurons in the spinal cord that process sensory information are spatially separate from motor neurons. WitrynaThe terms associated with regions of gray matter in the spinal cord include dorsal horn, lateral horn, and ventral horn. The dorsal horn contains sensory neurons, the lateral horn contains autonomic motor neurons, and the ventral horn contains somatic motor neurons. 5. Define gray commissure.
