title: Age-related reduction in 8th cervical ventral nerve root myelinated fiber diameters and numbers in man.
abstract: Reduction in the number of large myelinated nerve fibers in spinal nerve roots has been described previously. We observed a reduction in myelinated nerve fiber diameters which at least in part explains the apparent marked reduction in the number of large myelinated fibers with age.
