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. Webnerve fibers. In the myelinated nerve fibers, the impulses jump from one node to another node by saltatory conduction. •2. Insulating capacity: Myelin sheath has a high insulating capacity. Because of this quality, the myelin sheath restricts the nerve impulse within the single nerve fiber, and prevents the stimulation of neighboring nerve fibers
WebFeb 1, 2024 · Neurofibrils help in transmission of nerve impulses to and from the cell body. Centrosome is absent in the cyton. Mature nerve cells are called post-mitotic cells as they never divide. How do neurofibrils differ from nerve fibers? How do neurofibrils differ from nerve fibers? a.
