[29] According to Ho et al., sciatic nerve at low and high concentrations of Na and K in frog, axon and axoplasm degenerations occur and Schwann cell organelles decreases, mesaxon widens.
Internal and external mesaxons were apparent [Figure 2a].
(9) In the PNS, paranodal myelin loops contain cytoplasm that directly connects the Schwann cell body with the inner or outer mesaxons. Thus, the paranodal region of myelin is believed to have an important role in molecular transport between the Schwann cell body and compact or deep layers of myelin.
