Morphometric Study of Ventricular Myocardial Cells in the Bat ( Pipistrellus pipistrellus), Hamster ( Mesocricetus auratus) and Wistar Rat
A comparative morphometric study of ventricular myocardial cells of the West African insect-eating bat, Pipistrellus pipistrellus the hamster and the rat revealed significant differences in volume fractions of mitochondria, myofibrils, lipid bodies and T tubules. In the cells of the bat, mitochondri...
