Figure 1: Schematic diagram of vagal nuclei. (A) Depicted here is an anterior perspective of the medulla oblongata and vagal nuclei. On the right side of the medulla, afferent vagal nuclei are depicted including the spinal nucleus of trigeminal nerve (blue) and the nucleus tractus solitarius (orange). On the left side of the medulla, efferent vagal nuclei are depicted including nucleus ambiguus (red) and the dorsal motor nucleus (green). The vagus nerve forms via a series of nerve rootlets from the lateral portion of the medulla, which exits the cranium through the jugular foramen (black circle). The jugular ganglion of the vagus nerve is proximal to the jugular foramen whereas the no dose ganglion is distal. (B) Depicted here is a superior perspective of a transverse section through the medulla oblongata. Afferent vagal nuclei depicted include the spinal nucleus of trigeminal nerve (blue) and the nucleus tractus solitarius (orange). Efferent vagal nuclei depicted include nucleus ambiguus (red) and the dorsal motor nucleus (green). Olivary bodies (gray) are also depicted for orientation purposes [3]
