Osteoarthritis involves the entire joint, including the nearby muscles, underlying bone, ligaments, joint lining (synovium), and the joint cover (capsule). 1  Osteoarthritis also involves progressive loss of cartilage.
This allows the daughter and parent cells to have an equal amount of genetic material. The last stage is telophase, and this is where cytokinesis in animals takes place. When an animal cell begins to divide, it is attributed to a structure called a contractile ring. The contractile ring tightens tighter and tighter by a protein called myosin and eventually makes a burrow called a cleavage burrow..
Cytokinesis in the Animal Cell written by: Jarod Saucedo â¢ edited by: Amanda Grove â¢ updated: 1/17/2012 Cytokinesis in animals is an important cellular step that allows animal cells to divide through mitosis and meiosis. Read this study guide to learn how these two steps contribute to cellular division that allows animal cells to divide whether they are somatic or sexual.
