WebJan 23, 2024 · The neuronal cell bodies are present mainly in the ganglia while the axons (nerve fibers) are forming the peripheral nerves. Nervous fibers A nerve fiber consists of an axon enveloped by a special sheath. Nerve fibers exhibit differences in their enveloping sheaths, related to whether the fibers are part of the central or peripheral nervous system. WebANSWER: There is no real difference, since they are both capable of impulse conduction away from a neuron. Neurofibrils are axon subunits that are bundled together to make up a single nerve fiber. Neurofibrils are cytoskeletal intermediate filaments maintaining cell shape, but they do not conduct impulses.
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… WebElectron microscopy, developed throughout the twentieth century, recognized some of these fibrils within nerve fibers as being also tubular.
