The outer aspect is composed of white matter, which passes between the brain and spinal cord and gray matter lies centrally. Some cells constitute relay stations for sensory nerves passing from spinal cord to the cerebrum. The vital centers consisting of groups of cells associated with autonomic reflex activity lie in the deeper area. These are the cardiac, respiratory, vasomotor and reflex centers for vomiting, coughing, sneezing and swallowing.
