Transmission Electron Micrograph (TEM) of apical portion of two cells, one ciliated, in a turtle's urinary bladder. Cilia can be seen to be closely involved with filaments of the glycoprotein coat of the cell. Notice tight attachment adjacent to cell membranes of these epithelial cells at apex. Notice microtubules within cilia. Magnification: 43,000x @ 8 x10 inches.
