Compare incomplete tetanus with wave summation
A) In incomplete tetanus, the muscle is continuously contracting with no relaxation. Wave summation refers to an increases length of the relaxation phase with higher degrees of tension. B) In incomplete tetanus, the muscle is producing near-peak tension during rapid cycles of contraction and relaxation. Wave summation refers to the addition of one twitch to another. C) In incomplete tetanus, the muscle is continuously contracting with no relaxation. Wave summation refers to the addition of one twitch to another. D) In incomplete tetanus, the muscle generates a slightly higher maximum tension with each successive stimulus after each relaxation phase. Wave summation refers to a muscle continuously contracting with no relaxation. E) In incomplete tetanus, the muscle is producing near-peak tension during rapid cycles of contraction and relaxation. Wave summation refers to rapid numbers of action potentials occurring over a period of time.
