Posterior proper fasciculus
Encyclopedia
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
.
Posterior column
thumb | right | Cross-section of the spinal cord Posterior column or dorsal column refers to the area of white matter in the dorsomedial side of the spinal cord. It is made up of the fasciculus gracilis and fasciculus cuneatus and itself is part of the dorsal funiculus...

Funiculus
The cerebrospinal fibers consist of numerous nerve fibers collected together and enclosed in membranous sheaths. A small bundle of fibers, enclosed in a tubular sheath, is called a funiculus; if the nerve is of small size, it may consist only of a single funiculus; but if large, the funiculi are...
