Explanation:
Bone tissue may be of two types; compact bone tissue that form the outer hard covering of bones and spongy bone tissue that form inner soft portion of bone. Osteon are found in compact bone.
Osteons are cylindrical structures composed from clustre of Osteocytes and layers of extracellular matrix around a central canal connected by canaliculi for the transportation of blood. The haversian canal is surrounded by lamella that comprises the osteon. Osteons run parallel to long axis of bones and present in bones of many mammals, reptiles and birds. In some bones the stress or pressure in applied from few directions and osteons are aligned in that direction so they provide protection from bone bending or fracturing from compressive forces.
Answer:
Explanation:
This question appear wrong. Cells do not divide other cells as cells have the ability to undergo individual cell division as seen in cell cycle. However, there are some factors that could lead to increased cell division; factors such as cancer and viral infection can lead to increased division of certain cell types.
There is also a cell organelle present in mammalian cells that facilitates the division of a cell - this organelle is known as centriole. Centrioles do this by assisting in the separation of chromosomes during the mitotic phase of the cell cycle.
