Solitary tract - Wikipedia
The solitary tract (tractus solitarius or fasciculus solitarius) is a compact fiber bundle that extends longitudinally through the posterolateral region of the medulla oblongata. The solitary tract is surrounded by the solitary nucleus, and descends to the upper cervical segments of the spinal cord. It was first named by Theodor Meynert in 1872.

The solitary tract is a heavily myelinated fiber bundle that extends from the level of the facial nucleus in the caudal pons to the spinomedullary junction. A large region of the dorsal tegmentum, mostly medial and dorsal to the tract, is the solitary nucleus.
Anatomy of the Rostral Nucleus of the Solitary Tract
The nucleus of the solitary tract (NST) is a major sensory nucleus in the dorsal medulla that receives cardiovascular, visceral, respiratory, gustatory, and orotactile information [1,2]. The NST begins at the level of the pyramidal decussation near the cervical spinal cord and extends rostral to the caudal part of the dorsal cochlear nucleus [3].
