Verified
If one nerve stimulus arrives at a muscle fiber so soon that the fiber does NOT relax at all from the previous twitch, the most likely result will be ________.
A) fatigue
B) spasm
C) incomplete tetanus
D) complete tetanus
E) wave summation
Incomplete Tetanus
A condition where muscle fibers produce almost peak tension during rapid cycles of contraction and relaxation.
Complete Tetanus
A condition of sustained muscle contraction resulting from rapid, repetitive stimulation that does not allow for relaxation between stimuli.
Fiber Relax
A process where muscle fibres return to a state of rest and lengthen after contraction or tension.
- Explain the processes leading to different contraction responses such as tetanus and treppe.

Final Answer :
D
Explanation :
When multiple nerve stimuli arrive at a muscle fiber in rapid succession, preventing it from relaxing between twitches, the result is a smooth, sustained contraction known as complete tetanus. This occurs because the stimuli are so frequent that the muscle does not have time to relax at all between them, leading to a continuous contraction.
