When an axon in a myelinated peripheral nerve is severed the distal section of the axon that was separated from the cell body deteriorated and is phagocytosed by neurolemmocytes. The neurolemmocytes then shape a regeneration tube, as the fraction of the axon that is linked to the cell body begins to develop and display ameboid progression. neurolemmocytes. To help guide the growing axon tip to the proper destination, the neurolennocytes of the regeneration tube secrete chemicals. This is how severed nerves can be re-attached and function can return provided the procedure is performed prior to nerve death. Peripheral axons have a greater ability to regenerate than those of the central nervous system.
