The posterior proper fasciculus (posterior ground bundle; posterior basis bundle) arises from cells in the posterior column; their axons bifurcate into ascending and descending branches which occupy the ventral part of the funiculus close to the gray column.

They are intersegmental and run for varying distances sending off collaterals and terminals to the gray matter.
