Posterior external arcuate fibers

The posterior external arcuate fibers (dorsal external arcuate fibers) take origin in the accessory cuneate nucleus ; they pass to the inferior peduncle of the same side.
It carries proprioceptive information form the upper limbs and neck. It is an analogue to the dorsal spinocerebellar tract for the upper limbs. In this context, the "cuneo-" derives from the accessory cuneate nucleus, not the cuneate nucleus. (The two nuclei are related in space, but not in function.)
The term "cuneocerebellar tract" is sometimes used to collectively refer to the posterior external arcuate fibers.
The term "cuneocerebellar tract" is also used to describe an exteroceptive component that take origin in the gracile and cuneate nuclei; they pass to the inferior peduncle of the same side.
It is uncertain whether fibers are continued directly from the gracile and cuneate fasciculi into the inferior peduncle.
