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..
How does cytokinesis differ in animal and plant cells? In animal cells cytokinesis occurs when a cleavage furrow (a groove in the cell surface) forms around the cell. This furrow narrows the cell across the centre and eventually p â¦ inches it into two new cells. In plant cells a cleavage furrow does not form. Instead a cell plate forms across the equator of the cell.
