cells are genetically encoded to preform the tasks needed to sustain life and carry out reproduction. so it would depend on what kind of cell.
Whenever they feel like it, there is no set time
Yes, they divide, and as they divide, they create bone matrix and collagen fibers. As the osteoblasts become surrounded by the bone matrix, it hardens, enclosing the cells in a lacuna, transforming them into osteocytes. Osteocytes cannot divide.
cell division is how organisms grow
In bone, there are osteoblasts (cells which build bone) and osteoclasts (cells which break down bone). In the bone marrow and spongy bone, there are hematopoietic cells (cells which make blood). Bone is a type of connective tissue that is made of specialized cells that all work together for a common function. Their cellular and extracellular matrix is what makes bone cells so unique.
Bone cells that resorb bone tissue.
Nerve cells send signals to your brain and bone cells provide formation & development.
Usually bones cells
bone marrow cells will divide through binary fission
blood cells
Yes, they divide, and as they divide, they create bone matrix and collagen fibers. As the osteoblasts become surrounded by the bone matrix, it hardens, enclosing the cells in a lacuna, transforming them into osteocytes. Osteocytes cannot divide.
When bone cells divide they must produce cells exact copies of themselves.
Labile cells (the kinds of cells that can divide throughout their lifetime) normally do so within the organ they constitute. Some examples of labile cells are skin cells, cells of the gastrointestinal tract, and blood cells; however, blood cells divide in the bone marrow and lymphocytes divide in the lymph nodes. Other kinds of cells in the body are either stable cells (that do not normally divide--this includes nerve cells) and permanent cells (that do not have the ability to divide.)
Cells divide as the zygote becomes a fetus with growth and development into babies when born, cells also divide with growth after birth into adulthood and to replenish and renew damaged or lost cells.
In order to replace the cells that are dieing
When a person breaks a bone or has a cut, the cells at the edge of the injury are stimulated to divide rapidly. The new cells that form begin to heal the break or cut. As it heals, the cells stop dividing and growing.
A bone marrow biopsy is the removal of soft tissue from a bone.
No, red blood cells cannot perform cell division as they do not have a nucleus. They are instead produced in the bone marrow by the division of stem cells.
Liver cells divide about once a year, and neurons (nerve cells) never divide once we are born (and when they are mature).
