Tetanus of muscles is described as Select one: a. action potential frequency is high enough that no relaxation of muscle fibers occurs. b. a muscle produces constant tension during contraction. c. a muscle produces an increasing tension during contraction. d. a muscle produces increasing tension as it shortens. e. a muscle produces tension, but the length of the muscle is increasing.

A tetanic contraction occurs due to repeated stimuli at short intervals. In this situation, the muscle fiber does nor relax and contracts again. It is a process of sustained contraction of muscles, which evoke when the motor nerve innervates a skeletal muscle and emits the action potential at high rate. The muscles become hyperactive in this condition.

Tetanus of muscles is described as action potential frequency is high enough that no relaxation of muscle fibers occurs (Option a).

When stimuli are slow enough, then the tension in the muscle fibers relaxes between different successive muscle contractions.

A tetanic contraction is a continued muscle contraction that occurs when motor nerves innervating a muscle emit action potentials at high frequency.

In consequence, tetanic contractions are caused by the repetitive activation of muscles and the summation of responses to different successive stimuli (i.e., twitches overlap, thereby producing tetanic contraction).

In conclusion, tetanus of muscles is described as action potential frequency is high enough that no relaxation of muscle fibers occurs (Option a).
