This slide passes through the caudal medulla. Second order neurons, within the nucleus gracilis give rise to fibers which decussate and begin to pile up ventrally as the first component of the medial lemniscus.

We will remind you repeatedly of the great clinical importance of knowing the level at which motor and sensory pathways cross the midline. For the DC-ML pathway the decussation occurs here, at the level of the caudal medulla.

One easy way to trace the pathway rostrally is to just click on the red "rostral" numbers above. If you click on "1" you will go rostrally by one slide, etc.
