Teased myelinated nerve fiber

WebbFor example, in the classic book on The Anatomy of the Nervous System, by Ranson ( 1922, p. 47), the nerve fibers were classified as follows: 1. Myelinated fibers with a neurilemma found in the peripheral nervous system, especially in the cerebrospinal nerves. 2. Myelinated fibers without a neurilemma, found in the central nervous system. WebbThe beaded form of myelinated nerve fibers When the nerves are lightly stretched and fixed by freeze-substitution, their fibers show the form-change termed "beading" which consists of a series of undulating constrictions and swellings in the internodes. This form change has not ordinarily been seen in chemically fixed nerves, or when it has, …
