title: [Pathology of peripheral nerves (elementary lesions, their development and different types of neuropathies) (1st part)].
abstract: The ultrastructural features of the normal components of the endoneurium are described. The sequence of events of axonal (wallerian) and segmental demyelination are enumerated. The process of ageing in the peripheral nervous system is analysed.
