Metachronal rhythm: A metachronal rhythm or metachronal wave refers to wavy movements produced by the sequential action (as opposed to synchronized) of structures such as cilia, segments of worms or legs. These movements produce the appearance of a travelling wave.AxonemeJoubert syndromePericentriolar material: Pericentriolar material (PCM, sometimes also called pericentriolar matrix) is an amorphous mass of protein which makes up the part of the animal centrosome that surrounds the two centrioles. The PCM contains proteins responsible for microtubule nucleation and anchoring including γ-tubulin, pericentrin and ninein.TRPP: TRPP (Transient Receptor Potential Polycystic) is a family of transient receptor potential ion channels which when mutated can cause polycystic kidney disease.Arthur Biedl: Arthur Biedl (4 October 1869 – 26 August 1933) was an Hungarian pathologist born in what today is Comloşu Mic, Romania.PKD domain: B:353–424 A:1363–1442 A:1363–1442Flagellar motor switch: In molecular biology, the flagellar motor switch is a protein complex. In Escherichia coli and Salmonella typhimurium it regulates the direction of flagellar rotation and hence controls swimming behaviour.Hes3 signaling axis: The STAT3-Ser/Hes3 signaling axis is a specific type of intracellular signaling pathway that regulates several fundamental properties of cells.Janin PlotTanycyteKinesinParamecium: Paramecium (, http://www.merriam-webster.Sustentacular cellOlfactory receptor: Olfactory receptors expressed in the cell membranes of olfactory receptor neurons are responsible for the detection of odor molecules. Activated olfactory receptors are the initial player in a signal transduction cascade which ultimately produces a nerve impulse which is transmitted to the brain.Mischocarpus pyriformis: Mischocarpus pyriformis, known as the pear fruited tamarind is a rainforest tree of eastern Australia. Occurring from Seal Rocks, New South Wales to as far north as Cooktown in tropical Queensland.Centrosome cycle: Centrosomes are the major microtubule organizing center (MTOC) in mammalian cells. Failure of centrosome regulation can cause mistakes in chromosome segregation and is associated with aneuploidy.Morphant: An organism which has been treated with a morpholino antisense oligo to temporarily knock down expression of a targeted gene is called a morphant.Microtubule: Microtubules ([+ tube] + [are a component of the [[cytoskeleton], found throughout the [[cytoplasm. These tubular polymers of tubulin can grow as long as 50 micrometres and are highly dynamic.Mechanobiology: Mechanobiology is an emerging field of science at the interface of biology and engineering. It focuses on the way that physical forces and changes in cell or tissue mechanics contribute to development, physiology, and disease.Multiple patterning: Multiple patterning (or multi-patterning) is a class of technologies for manufacturing integrated circuits (ICs), developed for photolithography to enhance the feature density. The simplest case of multiple patterning is double patterning, where a conventional lithography process is enhanced to produce double the expected number of features.Field emission probesTubulin: Tubulin ([+ -in]) in [[molecular biology can refer either to the tubulin protein superfamily of globular proteins, or one of the member proteins of that superfamily. α- and β-tubulins polymerize into microtubules, a major component of the eukaryotic cytoskeleton.Vg1 ribozyme: The Vg1 ribozyme is a manganese dependent RNA enzyme or ribozyme which is the smallest ribozyme to be identified. It was identified in the 3' UTR of Xenopus Vg1 mRNA transcripts and mouse beta-actin mRNA.
