Veterinary anatomy. 328 GENEMAL CONSIDEBATIONS ON TEE DIGESTIVE (Unstriped or smooth bands of nmscles are composed of long fusiform cells â with staff-shaped, elongated nuclei, the cells varying from l-1125th to l-50th of an inch in length, and from l-5625th to l-1125th of an inch in breadth.) c. When the organs are lodged in one of the great splanchnic cavities, such as the chest or abdomen, they have a third mem- braneâa serous layer, which lines the cavity, and is reflected around the viscera contained in it, so as to envelop them more or less completely. This layer has, therefore, an adherent face, applied either against the walls of the cavity or the external surface of the splanchnic organs; and a free face always in contact with itself. A serous membrane is composed of two layers: a deep, connective portion, analogous to the mucous cerium; and a superficial, which is only pavement epithelium. The free surface of this epithelium is perfectly smooth, and lubricated by a limpid serosity to facilitate the gliding of the parts the membrane covers. (The epithelium is a simple tesselated layer of flattened and polygonal nucleated cells, about 1â1200ih of an inch in diameter). 2. The solid organs are either contained in the splanchnic cavities or situated outside them, in the midst of connective tissue, which, in condensing around them, often forms a fibrous covering. Like the hollow organs, they are singleâ spleen, liver ; or in pairsâkidneys ; and symmetrical or asymmetrical. They are retained in their situation by their vessels and nerves, by adherence to the neighbouring organs, or by particular serous attachments. With the exception of the lungs of animals that have respired, all the solid organs have a density greater than water. Their weight and volume offer numerous diflferences, which are individual or relating to the species to which they belong. Nevertheless, each organ pos- sesses a c
