Funiculus (neuroanatomy)
A funiculus is a small bundle of axons, enclosed by the perineurium. A small nerve may consist of a single funiculus, but a larger nerve will have several funiculi collected together into larger bundles known as fascicles. Fascicles are bound together in a common membrane, the epineurium.
Funiculi in the spinal cord are portions of white matter.
Examples include:
