Which one of these is a function of smooth muscle

• Thermogenesis

• Synchronous rhythm

• Integumentary

• Stabilisation

What is the percentage of contractile cardiomyocyte cell?

• 99.9%

• 98%

• 95%

• 99%

What is the function of a Desmosome?

• They are part of the cardiac muscle sarcolemma

• Enable electric coupling (form channels between adjacent cardiomyocytes)

• Aid in the action of the sliding filament theory

• Anchor the cells together; keeps the cardiomyocytes from pulling apart during contraction.
