Quizplus · Accepted Answer

Gray commissures contain axons that cross from one side of the spinal cord to the other. Anterior and posterior white columns contain ascending and descending tracts that do not cross sides. Lateral gray horns and posterior gray horns contain neuron cell bodies and dendrites, not axons that cross the midline.
