Abstract
An EM study of trochlear nerves obtained from human fetuses of 9.2 and 10 cm crownrump length (10 and 13 wk respectively) revealed the presence of collagen fibrils either in spaces which were bound exclusively by cytoplasmic processes of Schwann cells, or within closed vesicles set in such cytoplasmic processes. The role of the Schwann cells in the production of the endoneurial collagen was discussed.
