Surface ultrastructure of the mucosa of the soft palate in the vervet monkey.

The ullrastructurc of the surface of epithelial cells has been described by several workers [Wolf 1967, 1968; Bliimckc and Morgcnroth 1967; Whittaker and Adams 1971], All of these showed some form of fine folding on the surface of the cells studied. So constant a finding are these line surface folds that Marowitze/ at. [1970] concluded that their presence is a sign of good tissue processing. Confusion exists however in the interpretation of the appearance of the various types of surface folds. This paper links the two dimensional appearance of the surface folds seen in a transmission clectronmicrograph with the three dimensional appearance seen with the scanning electron microscope.
