Question
Skeletal and cardiac muscle are similar in which of the following ways? both muscles contain type I, IIa, and IIx fibers both muscles are under voluntary control both muscles contain fibers that are branched both muscles are composed of striated fibers
Solution
Skeletal and cardiac muscles are similar in that both are composed of striated fibers. Striated muscle tissue is a muscle tissue that features repeating functional units called sarcomeres. The presence of sarcomeres manifests as a series of bands visible along the muscle fibers, which is responsible for their striated appearance and gives them their name.
However, they differ in other aspects. Skeletal muscle fibers are not branched, unlike cardiac muscle fibers. Also, skeletal muscles contain type I, IIa, and IIx fibers, while cardiac muscles do not. Lastly, skeletal muscles are under voluntary control, meaning we can consciously control them, while cardiac muscles work involuntarily, without our conscious control.
