KROK 1 2007 – Question 18 · 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 shortening of the previous single muscle contraction?
- A. Muscle contracture
- B. Partial tetanus
- C. A series of single contractions
- D. Asynchronous tetanus
- E. Holotetanus
Hint
Compare the stimulus interval with the phases of a single twitch: an impulse arriving before relaxation starts adds to the unfinished contraction, so tension never dips.
