Compared to studying muscle function in vivo,using an isolated single muscle fiber to study muscle fatigue provides which of the following advantages?
A)measurements of ions and metabolites within fiber possible
B)force production of the single fiber can be measured
C)environment identical to in vivo conditions
D)Both A and B are correct

Question

Quizplus · Accepted Answer

Studying an isolated single muscle fiber allows for measurements of ions and metabolites within the fiber as well as force production of the fiber, which cannot be done in vivo. The environment may not be identical to in vivo conditions, but this is not necessarily a disadvantage. Therefore, both A and B are correct.
