CIL:39209, Tetrahymena pyriformis, cell by organism, eukaryotic cell, Eukaryotic Protist, Ciliated Protist. In Cell Image Library

A cross section of the cell (ventral side up) through the buccal cavity showing basal bodies of the 3 membranelles (1, 2 and 3) lying along the indented dorsal wall. A short segment of the oral ribs separates the membranelles from the undulating membrane that lies at the margin of the right wall. Basal body/cilium complexes of a kinety are found at the margin of the left wall. The left wall is covered by ER on its cytosolic side. TEM taken on 8/25/67 by R. Allen with Philips 200 operating at 60kV. Neg. 4,500X. The raw negative was scanned with an Epson Perfection V750 Pro and this high resolution image is best used for quantitative analysis.
