Scanning Electron Microscopy of Oviduct of Sheep in Luteal Phase ofEstrous Cycle

摘要

The mucosal surfaces of the sheep the infundibulum, ampulla and isthmus at the luteal phase were examined under the scanning electron microscope (SEM) to observe the cell types and cellular populations. Oviduct mucosa was found thrown into large number of longitudinal folds. The folds were lined with two types of cells namely ciliated and non-ciliated cells. The bunch of cilia was present on the apices of ciliated cells. Few non-ciliated cells interspersed within the group of ciliated cells were observed in infundibulum. In ampulla, the secretory cells equaled in number to the ciliated cells or outnumbered them.Secretory masses of different shape and sizes were spread over the ciliated and secretory cells. In Isthmus large number ofsecretory cells with few ciliated cells was present.
