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 References Neuroanatomy
