KROK 1 2007 – Question 73 · KROK (Medicine) · Physiology
Examination of an isolated cardiomyocyte revealed that it didn’t generate excitation impulses automatically. This cardiomyocyte was obtained from:
- A. Atrioventricular node
- B. His’ bundle
- C. Ventricles
- D. Sinoatrial node
- E. Purkinje’s fibers
Hint
Only specialised cells of the conduction system show slow spontaneous diastolic depolarisation; think which cardiomyocytes belong to the contractile working myocardium instead.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
