The membranes of these folds  the nerve shown in this page turned into a  When membranes of Schwann cells turned into myelin, hence this is a myelinated nerve. Myelin is basically constituted by fat and it was dissolved and lost during the preparation of this section. For this reason the region around the axons appears empty and unstained. It is highlighted in green.<br \/>\nThe loose connective tissue of the endoneurium is a placed between the nerve fibers but is scarce in most of the section. It is stained in light pink between nerve fibers.<br \/>\nThe unstained, empty spaces between nerve fibers and between groups of fibers are a technical artifact, due to tissue retraction, a defect introduced during the preparation of the material. <\/p>\n<p><img decoding=\"async\" src=\"https:\/\/mol-en.icb.usp.br\/wp-content\/uploads\/9-30.jpg\"\/><\/a><\/p>\n<p>Nerve (cross section).
