Osteocytes, also known as bone cells, have all the organelles found in other eukaryotic cells, such as a nucleus, mitochondria, cell membrane and endoplasmic reticulum. The major difference is that bone cells do not divide or undergo mitosis.
Osteocytes are eukaryotic cells with the characteristics and organelles of other eukaryotic cells. Among these is the nucleus that contains genetic material. Although they have genetic material, osteocytes do not undergo mitosis because, according to How Stuff Works, osteocytes are old, retired osteoblasts. They continue to function but at a reduced level. Osteocytes have a life of 25 years before they are replaced by other osteocytes.
The mitochondria in osteocytes is another organelle. This one produces the energy that propels the cell. The endoplasmic reticulum organelle is involved in protein synthesis. The cell membrane surrounds the cell's cytoplasm.
According to the University of Pennsylvania, osteocytes are critical to the bone matrix, which is made up of collagen and proteoglycans. Osteoblasts, the younger versions of osteocytes, form a layer upon which the matrix forms. Once this occurs, osteoblasts become part of the matrix and become osteocytes. The bone matrix survives only as long as the osteocytes survive. Once the osteocytes die, the matrix follows, and the process begins again.Learn More
In an animal cell, the cytoplasm is a semi-liquid substance that holds all the cell's organelles except the nucleus. It also acts as a repository for amino acids, sugars and other important nutrients used in the regular life of the cell. Finally, the cytoplasm stores a cell's waste until it is flushed from the cell.Full Answer >
The nucleus of a cell only divides once during mitosis, which occurs only in eurkayotic cells. Mitosis is the process in the cell cycle that separates the duplicate chromosomes and nucleus of a dividing cell.Full Answer >
Smooth muscle cells have the same organelles as other eukaryotic cells. The only difference between smooth muscle cells and other eukaryotic cell types is that smooth muscle cells contain many more mitochondria.Full Answer >
According to the University of Hamburg, the main difference between bone cells and muscles cells lies in their functions in the musculoskeletal system. Bone cells, which are commonly referred to as osteocytes, function to provide the architecture of the musculoskeletal system. Muscle cells, which are commonly referred to as myocytes, function to provide movement of the musculoskeletal system. These functions are representative of the structure of each type of cell.Full Answer >
