Centrosome (centrioles)
Centrioles play a crucial role in the movement of chromosomes during cell division. The cytoplasm that surrounds centrioles is referred to as the centrosphere. Together, centrioles and centrosphere are known as the centrosome.
Each centriole is encircled by a pericentriolar mass called mas- sules, satellite, or MTG. Centrioles are elongated, membraneless structures that display a cartwheel-like formation. Basal bodies are also considered a type of centriole. A centriole consists of 9 evenly spaced peripheral fibrils of tubulin arranged in a 9 + 0 pattern. Each peripheral fibril is a triplet. The hub, located in the central part of the proximal region of the centriole, is connected to the protein-composed radial spokes. These radial spokes link the hub to the tubules of the peripheral triplets.2.8.1 Functions
1. Centrioles in animal cells have a crucial function in initiating cell division by organizing spindle fibers between the two poles of the cell.
2. The positioning of centrioles during cell division determines the plane of division.
