All of the following cell types undergo cell division, EXCEPT:
Correct Answer: Cardiac muscle cell
Description: 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.
