The '''accessory cuneate nucleus''' is located [[Anatomical terms of location|lateral]] to the [[cuneate nucleus]] in the [[medulla oblongata]] at the level of the sensory decussation (the crossing [[axon|fibers]] of the posterior column/medial lemniscus tract). It receives input from [[Cervical vertebrae|cervical]] [[spinal nerve]]s and transmits that information to the [[cerebellum]]. These fibers are called cuneocerebellar (cuneate nucleus > cerebellum) fibers. In this function, the accessory cuneate nucleus is comparable to the [[Arm|upper extremity]] portion of the [[posterior spinocerebellar tract]]. |

The accessory cuneate nucleus is located lateral to the cuneate nucleus in the medulla oblongata at the level of the sensory decussation (the crossing fibers of the posterior column/medial lemniscus tract). It receives input from cervical spinal nerves and transmits that information to the cerebellum. These fibers are called cuneocerebellar (cuneate nucleus > cerebellum) fibers. In this function, the accessory cuneate nucleus is comparable to the upper extremity portion of the posterior spinocerebellar tract.
