The trigeminal tubercle or tuberculum cinereum[1] is a raised area upon (the caudal/inferior portion of) the lateral[2] dorsal/posterior aspect[3][2] of the medulla oblongata produced by the underlying spinal tract of the trigeminal nerve (cranial nerve V). It is situated just lateral to the tuberculum cuneatus (of nucleus cuneatus),[3] between the rootlets of the accessory nerve and posterolateral sulcus.
