9781130121667: The Adult Organisation of Paragordius Varius (Leidy)

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1903 Excerpt: ...the anterior end of the capsule. The retinal cells. In the cavity of the eye, besides the thin coagulum representing a fluid and some free spherical, non-nucleated masses, lie the retinal cells (Bet. C Figs. 5, 6, 13, PI. 1). In most of the individuals examined these are placed against the posterior concavity of the capsule, but in one male they filled the greater portion of the eye cavity. These are spindle-shaped small cells (Figs. 8, 13), with a small deep-staining nucleus (N Fig. 8); the cytoplasm usually nearly homogeneous, sometimes alveolar, non-refractive. The two ends of the cell are attenuated and drawn out into long fibres. Those nearest the capsule wall (E.Cap) are generally found attached to it in pyriform clusters; the cells lying deeper in the eye cavity may in some cases be seen to be attached to the others. There is not a single epithelial layer of these cells, nor do any of them appear to be entirely disconnected from the others, but they seem to form a connected whole. By iron-haematoxylin staining Ret. C Fig. 5, PI. 1) deep-staining fibres are to be found within these cells, staining in the same way as the chromophilic nerve fibres of the central nervous system. In each cell is at least one such fibre, which generally forms a loop around the nucleus, the loop often appearing ring-shaped. Sometimes a fibre is seen to end against the nucleus (N), but it is probable that in such a case the loop encircles the nucleus in such a position that it cannot be seen. These intra-cellular fibres may be traced to the capsule (Fig. 5 E. Cap), and there seem to enter the nerve bundles (Dors.N.B) of the latter; the terminal ends of these fibres become much attenuated, which would speak for their being outgrowths from the retinal cells into the nerves rat...
