Cilia and the life of ctenophores
TLDR
Post-embryonic patterns of comb row development in larval and adult stages are described and compared with regeneration of comb plates after surgical removal, and ciliary coordination has been elucidated by experiments on a variety of ctenophores. Expand
Critical Point Drying for Scanning Electron Microscopic Sthdy of Ciliary Motion
TLDR
Scanning electron microscopic study of tile pattern of ciliary coordination and the form of the ciliary beat is now possible and such stuidies have been made on the ciliate Opalina with this new technique. Expand
Flagellated ectosymbiotic bacteria propel a eucaryotic cell

  • Medicine, Biology
  • The Journal of cell biology
  • 1 September 1982
TLDR
That the ectosymbiotic bacteria actually propel the protozoan was shown, and this motility-linked symbiosis resembles the association of locomotory spirochetes with the Australian termite flagellate Mixotricha, except that in this case propulsion is provided by bacterial flagella themselves. Expand
Flagellar Development in the Protozoan Peranema trichophorum
TLDR
It was concluded that at least part of the control exerted overFlagellar length changes resides in the flagellum itself, and the kinetics of regeneration at different cell ages have been satisfactorily accounted for by a mathematical model. Expand
Mechanisms of Ciliary Co-Ordination in Ctenophores
TLDR
The results showed that the comb plates of cydippids and beroids are co-ordinated by mechanical forces arising from the movement of the plates themselves, and that ciliary co-ordinate may be entirely neuroid in lobate ctenophores. Expand
Actin pegs and ultrastructure of presumed sensory receptors of Beroë (Ctenophora)
TLDR
Investigation of the actin content and ultrastructure of two kinds of presumed sensory projections on the lip epidermis of beroid ctenophores showed that conical pegs contain a large bundle of densely packed, parallel microfilaments. Expand
Mechanical synchronization of ciliary beating within comb plates of ctenophores.
  • S. Tamm
  • Biology, Medicine
  • The Journal of experimental biology
  • 1 November 1984
TLDR
In cases where the beating of a comb plate is triggered by a ciliated groove, the cilia within the plate are synchronized by hydrodynamic coupling forces between them, not by electrical coupling between their cells as assumed previously. Expand
The ultrastructure of prokaryotic-eukaryotic cell junctions.
  • S. Tamm
  • Biology, Medicine
  • Journal of cell science
  • 1 August 1980
TLDR
The bacterial-devescovinid junctions are considered to serve mainly as attachment sites, and the membrane specializations at the sites of contact are discussed in this respect. Expand
Novel bridge of axon‐like processes of epithelial cells in the aboral sense organ of ctenophores
TLDR
The possibility that the bridge in Pleurobrachia is an electrical conduction pathway to balancers that coordinates tentacle‐evoked swimming responses of ctenophores, such as global ciliary excitation is discussed. Expand
Novel Structures Associated with Presumed Photoreceptors in the Aboral Sense Organ of Ctenophores
  • S. Tamm
  • Medicine, Biology
  • The Biological Bulletin
  • 1 October 2016
TLDR
This research presents a novel probabilistic procedure that allows for direct measurement of the response of the immune system to the presence of cadmium in Response to Tournaisian infectious disease. Expand
