Into What Units are the Myofibrils of Skeletal Muscle Organized

Question

Into what units are the myofibrils of skeletal muscle organized?
A) A discs
B) sarcomeres
C) Z discs
D) antagonistic pairs

Accepted Answer

The myofibrils of skeletal muscle are organized into sarcomeres, which are the basic functional units of skeletal muscle contraction. Sarcomeres are made up of thin and thick filaments that slide past each other, resulting in muscle contraction. A discs, Z discs, and antagonistic pairs are also components of skeletal muscle, but do not organize the myofibrils into functional units.
