|Title||Unpublished paper, 'On the general and minute structure of the spleen in man and other animals' by William Julian Evans|
|Creator||Evans; William Julian (fl 1843)|
|Description||Evans details the results of his investigations on the structure of the spleen. According to his analysis, the following are the component parts of this organ: first, a reticulated fibro-elastic tissue; secondly, a pulpy parenchyma, containing the Malpighian glands and the splenic corpuscles; thirdly, distinct cellular bodies; fourthly, the usual apparatus of arteries veins, lymphatics and nerves; fifthly, certain fluids; and lastly, the membranes or tunics by which it is invested. He describes the cells of the spleen as being formed of a lining membrane, continued from that of the splenic vein, and strengthened by filaments of the fibro-elastic tissue. The splenic vein communicates with these cells, at first by round foramina, then by extensive slits resembling lacerations; and it ultimately loses itself entirely in the cells. The cells themselves communicate freely with one another, and also with the veins of the parenchyma; and may therefore be considered as in some measure continuations of the veins, This structure constitutes a multilocular reservoir of great extensibility, and possessing great elastic contractility ; properties, however, which exist in a much less degree in the human spleen than in that of herbivorous animals; in which animals the cellated structure itself is much more conspicuous, and predominates over the parenchymatous portion. |
