Mitotic Cell Division And Mitotic Phases

Cells replicate themselves through a process called cell division. Two types of cell division occur in the body: mitotic cell division and meiotic cell division. Somatic cells (cells other than sex cells) divide by mitotic cell division, during which a parent cell divides to form two new

Myocardial Physiology

Myocardial cells have distinctive anatomic and physiologic characteristics. Under a microscope, striations are visible owing to the arrangement of actin and myosin as in skeletal muscle. T tubules increase the contact area of the cell membrane and extracellular fluid space. At rest, cardiac muscle obtains 99% of
