Abstract: Structure of the ductus endolymphaticus (DE) and saccus endolymphaticus (SE) was studied in Alligator mississippiensis and Prhynocephalus versicolor. The development of these structures was investigated in Alligator mississippiensis. The ultrastructure of the eptelium lining SE was observed in Phrynocephalus versicolor. The sE in the experimental animals was located in the duplication of dura mater. The lumen of the DE and SE was lined by a simple cuboidal or columnar epithelium. A dense content was observed in the lumen of all compartments of the SE and DE in the developmental stages of Alligator mississippiennsis. In the epithelial lining of the WE of Phrynocephalus versicolor cells with microvilli at the apical zone and invaginations of the basal cell membrane were revealed. A basal labyrinth was not discovered. In their cytoplasm light vacuoles and dark granules without a limiting membrane were observed. The lumen of the SE of Phrynocephalus versicolor was free of any electron dense material. A rich capillary network was formed in the subepithelial connective tissue. |
