WebA. Neurofibrils are confined to dendrite receptor areas and are consequently not found in nerve fibers. B. Neurofibrils are axon subunits that are bundled together to make up a single nerve fiber. C. Neurofibrils are cytoskeletal intermediate filaments maintaining cell shape, but they do not conduct impulses. D. Neurofilaments (NF) are classed as type IV intermediate filaments found in the cytoplasm of neurons. They are protein polymers measuring 10 nm in diameter and many micrometers in length. Together with microtubules (~25 nm) and microfilaments (7 nm), they form the neuronal cytoskeleton. They are believed to function primarily to provide structural support for axons and to regulate axon diameter, which influences nerve conduction velocity. The proteins that form neuro…
