A funiculus 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 fasciculi. Fasciculi are bound together in a common membrane, the epineurium.
