Canine Brainstem Drawing

Artist rendition of a dorsal view of the canine brainstem. The nucleus gracilis (orange) is located beside the midline at the caudal end of the medulla oblongata (myelencephalon). The nucleus receives touch and kinesthesia from the pelvic limb via the fasciculus gracilis.

The fasciculus cuneatus conveys touch and proprioception from the thoracic limb to the medial cuneate nucleus (green) The nucleus relays the information to the thalamus for conscious perception. (The fasciculus cuneatus also conveys subconscious proprioception to the lateral cuneate nucleus (yellow), for relay to the cerebellum.)
