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 fascicles. Fascicles are bound together in a common membrane, the epineurium.Siegel, A. & Sapru, H. (2011). Essential neuroscience. Philadelphia: Wolters Kluwer Health/Lippincott Williams & Wilkins.
Funiculi in the spinal cord are columns of white matter. Examples include: Anterior funiculus of the spinal cord Lateral funiculus of the spinal cord Posterior funiculus of the spinal cord
