Gregory Antipa (San Francisco State University) (2011) CIL:19537, Didinium nasutum, cell by organism, eukaryotic cell, Eukaryotic Protist, Ciliated Protist. CIL. Dataset

The proboscis of Didinium. While not well preserved, this image clearly shows the clockwise surface ridges that are elevated by ribbons of microtubules that are involved in supporting the buccal cavity during the process of ingesting prey. See the ribbons of microtubules in CIL:17451, 17452, & 15400. The extrusive organelles toxicysts and pexicysts reside just below the membrane of the proboscis plateau. This micrograph was taken in 1968 by G. Antipa on a Cambridge Mark IIA operating at 20kV. The negative magnification is 4760X. The raw film was scanned with an Epson Perfection V750 Pro. This image is available for qualitative analysis. Further details are available at Wessenberg, H. and Antipa, G. 1968. Studies on Didinium nasutum. I. Structure and ultrastructure. Protistologica 4:427-447 and 1970. Capture and ingestion of Paramecium by Didinium nasutum. J. Protozool. 17:250-270.

关于 Didinium 的喙部。尽管保存状况不佳，但此图像清晰地展示了呈顺时针方向的表面脊，这些脊由参与支撑口腔在摄食猎物过程中的微管束构成。请参阅 CIL：17451、17452 及 15400 中的微管束束带。外分泌器官毒囊和质囊位于喙部平台的膜下方。这张显微照片由 G. Antipa 于 1968 年使用工作在 20kV 的 Cambridge Mark IIA 拍摄。负像放大倍数为 4760X。原始胶片使用 Epson Perfection V750 Pro 扫描。此图像可用于定性分析。更多详细信息可参考 Wessenberg, H. 和 Antipa, G. 1968 年发表的《关于 Didinium nasutum 的研究。I. 结构与亚结构》一文，发表于 Protistologica 4:427-447，以及 1970 年发表的《Didinium nasutum 捕食和摄食 Paramecium》一文，发表于 J. Protozool. 17:250-270。
