Stentor coeruleus Tomographical cross-sections through a Stentor coeruleus. AZR = adoral zone of membranelles, MTR = microtubular ribbons, Ma = moniliform macronucleus. The microtubule ribbons are fully outstretched to give the cell body its maximum size. On the physiology of the microtubular ribbons see Hausmann/Hülsmann/Radek Protistology 3rd ed, Stuttgart, 2003.Scale bar indicates 50 µm. Sample from a tropical freshwater aquarium. Sampling date 3/2021. The image was built up using several photomicrographic frames with manual stacking technique. Images were taken using Zeiss Axioplan with Olympus OM-D M5 MKII.

Stentor coeruleus Tomographical cross-sections through a Stentor coeruleus. AZR = adoral zone of membranelles, MTR = microtubular ribbons, Ma = moniliform macronucleus, BC = buccal cavity. The microtubule ribbons are fully outstretched to give the cell body its maximum size. On the physiology of the microtubular ribbons see Hausmann/Hülsmann/Radek Protistology 3rd ed, Stuttgart, 2003.Scale bar indicates 50 µm. Sample from a tropical freshwater aquarium. Sampling date 3/2021. The image was built up using several photomicrographic frames with manual stacking technique. Images were taken using Zeiss Axioplan with Olympus OM-D M5 MKII.
