Morphology Of Lung Of Rana Ridibunda With Observations On Changes Occurring Under Different Conditions, Füsun Öztay
Turkish Journal of Zoology
The frogs used in this study were divided into three groups. The first group consisted of frogs collected from their natural habitat, and these animals were dissected immediately. The bodies of the frogs in the second group were totally submerged in water at +4 °C, and the third group of frogs was kept in a dry environment. The lung sections were examined under a light microscope after being stained. The lungs were found to have three folds: the primary, secondary and tertiary septa. Goblet cells were not only found among the ciliated cells but were also seen among pneumocytes. In …

The ultrastructural features of the intrinsic lingual muscles in the frog were investigated. The pieces obtained from the anterior part of the tongue were fixed in 3% gluteraldehyde and postfixed in 0.1% osmium tetroxide. Ultrathin sections stained with uranyl acetate and lead citrate were examined in a JEOL-100SX electron microscope. The muscle fibers were irregular in shape. The sarcoplasm was occupied largely by the myofibrils. In the same muscle fiber, longitudinal, transverse and oblique sections of the myofibrils were observed. Thus, regular transverse striation was prominent in some areas. In these areas, Z lines, I bands and A bands were …
