Webb14 okt. 2024 · The nerve fibers in the sciatic nerve contain both afferent and efferent nerve fibers, and have small- and large-diameter axons, but predominantly large-diameter axons (SI Appendix, Fig. S1A). These observations indicated that it might be not possible to distinguish between afferent and efferent nerve fibers based solely on the axon diameter. WebbIn myelinated nerves, three types of axonal injury are recognized: . Distal axonal degeneration: Injury of the perikaryon leads to “dying back” injury of the axon, which starts most distally and spreads proximally toward the perinuclear portion of the cytoplasm. Degeneration of the axon is accompanied by a breakdown of the myelin enveloping ...
