“…Ultrastructurally, the reaction changes in axotomized neurons which are not degenerating are first recognized one day after axotomy, appearing as a few NGVs and dense bodies in the cell bodies [124,125]. After three days, they become more conspicuous and are characterized by an extensive rER which is either fragmented or in a peripheral location [123,124,173,174,195]. These cells also contain many ribosomes and NGVs which are most abimdantly accumulated in the periphery and are intermingled with dense bodies and multivesicular bodies [173,174].…”
