title: [Number and thickness of myelinic fibres of the phrenic nerve of young and aged rats].
abstract: The phrenic nerve of albino rats was studied for age changes in number of fibres, myelin sheath thickness and axon calibre. There is no significant morphological differences between nerves from young and aged rats and no difference with age was found in the number of fibres, myelin sheath thickness and axon calibre.
