What are the axon sizes in dorsal roots?
7 answers
The sizes of axons in dorsal roots vary significantly across different studies, species, and developmental stages, reflecting a complex interplay of biological factors. In rats, the mean areas of myelinated and unmyelinated fibers in dorsal roots were measured as 13.72 μm² and 0.14 μm², respectively, indicating that both myelinated and unmyelinated central processes of dorsal root ganglion cells are smaller than their peripheral counterparts. This size discrepancy is further supported by findings in cats, where calibers of myelinated axons were symmetrical about the ganglion, but nonmedullated axons showed striking differences in size across the ganglion, with a significant decrease in microtubule densities in central processes compared to peripheral ones. In rabbits, the developmental trajectory of axon sizes in dorsal roots shows a significant increase from newborn to adult stages, with the mean axonal diameter and mean myelin thickness in dorsal roots increasing by 380%. This growth pattern contrasts with the age-related changes observed in rats, where the average overall axon diameter in the L4 dorsal spinal root increases in adult animals but decreases in old rats, suggesting senile atrophy. Further complexity in axon size is observed in the context of injury and regeneration. For instance, large-diameter dorsal root (DR) axons in mice showed the ability to elongate through a DR crush site but not a transection site, indicating that axon size may influence regenerative capacity. Additionally, electron microscopy studies have revealed that the critical diameter for myelination in the peripheral nervous system is about one micron, but in the central nervous system, it is 0.3 μ or less, highlighting a fundamental difference in myelination thresholds between these two systems. Moreover, the ultrastructural characteristics of primary sensory terminals within the spinal cord, which are influenced by axon size, show distinct patterns of degeneration following dorsal root transection, suggesting that axon size may also play a role in the vulnerability to injury and the process of degeneration. The relationship between axon size and conduction velocity, as well as the implications for sensory neuron classification into A and C cells, further underscores the functional significance of axon size in dorsal roots. In summary, axon sizes in dorsal roots are influenced by a multitude of factors including species, age, developmental stage, and pathological conditions, with significant implications for their function, regenerative capacity, and susceptibility to degeneration.
