Cytopharynx with numerous folded membrane ribs subtended by five or so microtubules. These microtubules have arms that bind to other microtubules and to the membrane of the cytopharynx and to surrounding vesicles of various sizes. The vesicles are uncoated and free of ribosomes. The vesicles are probably equivalent to the discoidal vesicles and/or to the 100nm vesicles; the latter arise from the endosomal pathway of Paramecium. Evidence for vesicle fusion to the cytopharynx membrane, between the ribs, can be seen. Bacteria and tips of cilia are present in the lumen of the cytopharynx. TEM taken on 4/6/72 by R. Allen with Hitachi HU11A operating at 75kV. Mag. 19,500X. The raw negative was scanned with an Epson Perfection V750 Pro and this high resolution image is best used for quantitative analysis.

细胞咽部拥有众多折叠的膜肋，由大约五条微管所支撑。这些微管延伸出臂，与其它微管、细胞咽部的膜以及周围不同大小的泡膜相结合。这些泡膜无被膜，且无核糖体附着。这些泡膜很可能等同于盘状泡膜或100纳米泡膜；后者源于变形虫的早期内体通路。在肋之间观察到泡膜与细胞咽部膜的融合证据。细菌和纤毛尖端存在于细胞咽部的腔内。由R. Allen于1972年4月6日使用日立HU11A在75kV下拍摄的透射电子显微镜图像。放大倍数为19,500倍。原始负片使用Epson Perfection V750 Pro扫描，此高分辨率图像适用于定量分析。更多详细信息请访问（http://www5.pbrc.hawaii.edu/allen/）。
