title: [Pathology of the peripheral nerve. (Teasing, the various degrees of denervation, onion bulbs) (2nd part)].
abstract: Anatomical data for the interpretation of teased fibres are described. The different degrees of degeneration in a peripheral neuropathy are enumerated and criteria to identify them are given. The onion bulb formation process is analysed and some morphologically different types are proposed.
