The Histological Study of the Frog´s Spleen
|
|
|
|
|
Abstract
|
|
|
Although frog spleen is generally structurally similar to that of mammals, the following differences were observed in our study. .
1. There is only one trabecula in the middle zone of tissue, and the capsule of the frog spleen does not contain smooth muscle fibers. .
2. The white pulp does not have uniform complete nodules, the lymphocytes in the white pulp are not packed close together, the white pulp contains large numbers of erythrocytes, and there are no central arteries or germinal centers in the spleen of frogs.
3. The arteries of frog spleen, unlike those in mammalian spleen, do not branch into central arteries in the white pulp, or into sheathed arteries in the red pulp.
4. Reticular tissue appears near the venous sinuses, but is not widely distributed throughout other splenic tissue.
5. Veins of frog´s spleen are distributed beneath the capsule and periphery of trabecula.
