Question

Cardiac muscle does not exhibit tetanus beacuse it has A. exclusively aerobic respiration. B. fast Ca2 channels. C. a long absolute refractory period. D. electrical synapses.

Answer 1

C, a long absolute refractory period.

Step-by-step explanation:

Tetanus is not possible in cardiac muscle tissue because cardiac cells have longer action potentials and a very long refractory period compared to other cells. This helps prevent the heart from cramping and seizing up.
