KROK 1 2010 – Question 21 · KROK (Medicine) · Physiology
During an experiment a skeletal muscle is stimulated by a series of electric impulses. What type of muscle contraction will be observed provided that each subsequent impulse comes in the period of shortening of the previous single muscle contraction?
- A. Muscle contracture
- B. Holotetanus
- C. Partial tetanus
- D. A series of single contractures
- E. Asynchronous tetanus
Hint
Compare the timing of each new impulse with the phases of a single twitch (shortening versus relaxation) to decide how successive contractions summate.
