1. True -False. If a statement is True, place a T to the left of it. If a statement is False, place an F to the left of it. Thin filaments in smooth muscles attach to Z discs. The majority of ventricular filling occurs during the period of atrial contraction known as the period of rapid filling. Closure of the atrioventricular valves occurs at the end of diastole/beginning of systole. Tetanus in skeletal muscles is the result of increasing the...
