Kaiser\). The primary afferents \(first order neurons in sensory pathways\) have their cell bodies \(pseudo-unipolar cells\) in the dorsal root ganglia, and enter the spinal cord via the dorsal \(posterior\) roots. The larger fibers, as shown here, enter the cord via the most medial part of the dorsal roots, and turn to ascend the cord, forming most of the posterior column; the somatotopic order, shown in the previous frame, is maintained. Primary afferents that travel in the posterior columns carry information about fine touch, vibration, proprioception and pressure.
