The beat pattern and beat frequency of cilia and flagella
in many kinds of eukaryote are controlled by changes in intracellular Ca2+ concentration. Ciliary movement in Paramecium comprises two kinds of ciliary strokes, the effective stroke and the recovery stroke, and shows metachronal coordination (Machemer, 1972). When Paramecia meet an obstacle, their cilia reverse the direction of their beat, allowing the organism to swim backwards (Jennings, 1906...
متن کاملEffect of Cilia Beat Frequency on Muco-ciliary Clearance
Background: The airway surface liquid (ASL), which is a ï‚uid layer coating the interior epithelial surface of the bronchi and bronchiolesis, plays an important defensive role against foreign particles and chemicals entering lungs.Objective: Numerical investigation has been employed to solve two-layer model consisting of mucus layer as a viscoelastic fluid and periciliary liquid layer as a New...

متن کاملBeat frequency of cilia from sites of purulent infection.
Mucociliary clearance depends on the interaction between cilia and mucus; it is delayed in the presence of purulent secretions. Nasal mucociliary clearance was examined by the saccharin method and nasal ciliary beat frequency by a photometric technique. Four groups were studied: normal controls, patients with bronchiectasis without nasal symptoms, patients with chronic mucopurulent sinusitis al...
