The
unmyelinated fibers showed the largest diameter (62%) varying from 0.25 to 0.75 [micro]m.
(D) Accumulation of mitochondria with clear cristae in a cross section of
unmyelinated fibers. (E) Accumulation of two cell types in the area of injury.
1), both nerves presented myelinated and
unmyelinated fibers, capillary vessels with endothelial cells and pericytes, nuclei of Schawnn cells and fibroblasts, and mast cells.
(16) When there are abnormal nerve growth and elevated levels of peripheral nerve sensitization, the nerves most often recruited are C-fibers,
unmyelinated fibers largely associated with both peripheral and central neuropathic pain.
