At the fine structural level, a longitudinal section through a mature sperm shows the decondensed nuclear region (N) in the base, the caplike region (arrow) housing the radial fibrils, and the cross-striated spike. Bar = 1 ^m. FIGURE 7. The cross striated appearance of the spike is apparent at higher magnifications. Note the numerous 6 nm filaments running perpendicular to the cross-striations. Bar = ^m. FIGURE 8. The spike terminates in a 50 nm bulbous tip. Bar = nm

FIGURE 8. The spike terminates in a 50 nm bulbous tip. Bar = nm. FIGURE 9. Occasionally the cross striations of the spike are observed to be out of register, indicative of the anastomosing radial fibrils of the cap-like region. Bar = a 35 ± nm periodicity. Numerous 4-7 nm filaments run longitudinally between the dense bands of the cross striations and both filaments and cross striations run the length of the spike terminating in a 50 nm spike tip (Fig. 8). The cross striations of the spike are occasionally out of register (Fig. 9), indicative of the anastomosing radial fibrils from the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
