Abstract
1.1. The ventricular tissue of the hibernating ground squirrel, Citellus lateralis, has been shown to be ultrastructurally similar to non-hibernating mammalian hearts.2.2. The sarcolemma, mitochondria, golgi zones, nuclei and myofibrils appear similar to those of other mammals. Internal and peripheral cell membrane couplings are similar to those of six non-hibernating mammals previously examined.3.3. These data are in conflict with other previous investigations.4.4. Additionally no ultrastructural difference was observed between active (37°C) and hibernating (5°C) squirrel hearts.5.5. These data suggest that the physiological differences between hibernators' and non-hibernators' hearts are due to differences in molecular configurations.
