Through Nerve, Connective tissue and Spinal cord
A nerve fascicle is enclosed by perineurium, a layer of fascial connective tissue. Each nerve fiber in the nerve fascicle is also enclosed by a connective tissue layer of endoneurium. Bundles of nerve fascicles are called fasciculi and are constituents of the nerve trunk of a nerve. A main nerve trunk may contain a great many fascicles enclosing many thousands of axons (or nerve fibers).
In neuroanatomy, different tracts in the spinal cord are bundled into fasciculi such as the medial longitudinal fasciculus. In the spinal cord, fasciculi are bundled into columns called funiculi such as the anterior funiculus.
