| Popis: | 1. 1. The myocardial cells of the flesh fly, Sarcophaga bullata , have been studied using conventional micro-electrode techniques. These studies indicated that an initial period of aertation or oxygenation was necessary to maintain the heart. 2. 2. The range of values, for the action and resting potential were 45 ± 8 mV and 57 ± 11 mV respectively with negligible or no overshoot. 3. 3. These studies indicate that the intracellular potentials from the myocardial cells of the flesh fly can vary in amplitude, rate and duration from cell to cell and within the same cell. 4. 4. The wave form is complex and commonly shows pacemaker characteristics as well as fast spikes which suggests a neural involvement. |
