Heart (Myocyte - except after MI) and brain cells (Neurons)
muscles and nerve cells
because they have more bacteria cells, since bacteria divide faster then somatic cells.
yes
The slowest dividing cells in the human body are the nerve cells. Nerve cells generate and conduct electrical impulses, allowing communication between the central nervous system and the rest of the body.
Yes, endothelial cells divide. It is important that these cells divide to replace old/dead cells and to create new blood vessels.
The cells divide into two daughter cells, to make way for replication.
because they have more bacteria cells, since bacteria divide faster then somatic cells.
No, human cells divide by mitosis and meiosis.
Cells alway divide using myiosis or mitosis, this differs per cell. In a human most cells divide using mitosis, a human is a mammal so there's your answer
yes
blood cells
the cells which must help for a human's growth undergo it, in other words most do
65 times a day
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.)
Liver cells divide about once a year, and neurons (nerve cells) never divide once we are born (and when they are mature).
The fastest dividing human cells are epithelial cells. These form the skin and line the cavities of the body. They need to divide quickly and replace themselves due to physical wearing away of the cells. Skin cells divide once every 20-30 minutes
They don't. Some grow and divide all the time (skin cells) and some never do (nerve cells) and some only at times when needed.
Most human cells when placed in a dish will not divide. The majority of cells that make up a human are post-mitotic. They have differentiated and specialized to carry out physiological functions for the body and have lost their capacity for division. However, a small percentage of human cells are stem cells or progenitor cells and do have a capacity to divide and if cultured under the correct conditions will undergo mitosis. There is a slight caveat - whenever you're culturing a cell in a dish, you are taking a cell out of its normal environment and putting it under very unnatural circumstances. Thus, it is not unknown for cells to behave oddly in a dish - cells that should divide don't because we don't understand the conditions necessary to promote their division. And sometimes cells that shouldn't divide do because we have subjected them to unnatural conditions that alter their identity and behavior.
