<prompt> All of the following cell types undergo cell division, EXCEPT:PericyteCardiac muscle cellSmooth muscle cellSatellite cell of skeletal muscle  <response>: Myocyte cell division in the human hea ceases a few weeks after bih. Thereafter, enlargement of the hea is as a result of cell hyperophy or the laying down of collagen in the extracellular space. DNA turnover is almost undetectable except in pathologic states. Approximately 20 of myocytes in the human hea have two nuclei, so that cell separation, rather than mitosis, could bring about a small increase in the total cell number.
