KROK 1 2007 – Question 200 · KROK (Medicine) · Physiology
In course of an experiment a skeletal muscle is being stimulated by a series of electric impulses. What type of muscle contraction will arise, if every subsequent impulse comes in the period of relaxation of single muscle contraction?
- A. Partial tetanus
- B. Asynchronous tetanus
- C. A series of single contractions
- D. Muscle contracture
- E. Holotetanus
Hint
The result depends on whether the next stimulus falls in the contraction or the relaxation phase of the previous twitch, so the muscle is only partly relaxed when re-excited.
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.
