On the issue of suturing peripheral nerves and dorsal roots of the spinal cord

To what extent the regeneration of peripheral nerves after injury is a question resolved in a positive sense, and there is only a dispute about the mechanism of this regeneration—the regeneration of the spinal cord and, in particular, the posterior roots, is still denied by the majority of those who have worked on this issue.

Studying the literature on the question that interests us, we see that the regeneration of the central nervous system in warm-blooded and cold-blooded animals is not the same. So Müller (1864) 102) after the removal of the entire tail in a newt and a lizard, saw a complete regeneration of the spinal cord and intervertebral nodes in the newly formed tail. Masius and Vanlair (according to Stroebe) (1869) saw in frogs the regeneration of fleshy and non-fleshy fibers and even ganglion cells after cutting a piece 2 mm long from the spinal cord. The possibility of regeneration of the spinal cord in reptiles and amphibians is also confirmed by Fraisse (1885) (according to Stroebe).
