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..
These organelles are specified to perform certain activities that are important for the survival of the cell. All the cells function together in coordination with each other and help the organism to survive. The functions of animal cell is carried out by the different cell organelles. The organelles of the cell function as a unit and regulate the activities of the cell. The different cell organelles and their functions are as follows:
