Funiculus (neuroanatomy)

A funiculus or column is a small bundle of axons (nerve fibres), 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:
 * Anterior funiculus of the spinal cord
 * Lateral funiculus of the spinal cord
 * Posterior funiculus of the spinal cord
 * Funiculus separans of the rhomboid fossa
