Difference between Incomplete and Complete Tetanus?

Question

What's the difference between the two? Could you also please explain to me further these two muscle contraction?

Thanks, I'm really confused between the two.

Answer 1

With incomplete tetanus muscles contract but there is a period of relaxation between contractions.  As shown on a graph, it looks like a wave.  With complete tetanus, there is no relaxation between contractions and on a graph, this is represented by a straight line.  Tetanus effects only striated skeletal muscles, not cardiac (heart) muscles.

Answer 2

Incomplete tetanus - the muscle relaxes slightly before the next contraction.

Complete tetanus - the muscle does not relax at all betweeen stimuli
