Fig. 20. An electron micrograph of the posterior third of the meridional row area in a normal rat lens when viewed in cross section. The basal extremity of a newly elongating cell (E ) seemingly has no alternative other than to assume the position dictated by the overlying capsule (C) and the presence of previously deposited lateral (L) and subjactent (S) fibers. Note the staggered arrangement of the nuclei (N) of the meridional rows.
