Definitions of NERVE FIBRES
Sort: Oldest first
By Henderson, I. F.; Henderson, W. D.
In the nerves of the higher animals, two forms of nerve fibre exist-the tubular, and the gelatinous. In the minute fibrils or tubules, Tubuli nervei, full of nervous matter, which constitute the former, there is a difference between the central and peripheral portion :-the former has been called the axis cylinder and primitive band; the latter, the medullary or white substance of Schwann,-being that to which the peculiarly white aspect of cerebrospinal nerves is principally due. In the gelatinous fibre, no tubular envelope can be distinguished, and the white substance of Schwann seems to be wanting. It contains numerous cell-nuclei. See Neurine.
