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..
The main difference between cytokinesis in animal cells and cytokinesis in plant cells is how the division occurs. In animal cells there is a formation of a cleavage furro â¦ w which gradually squeezes the cell in half. In plants cells they form a cell plate that gradually divides the cell in half.
