What are the two main types of skeletal muscle found in the human body?

Skeletal muscle fibers can be categorized into two types: slow-twitch (Type I) and fast-twitch (Type II).

Type I muscle fibers are more efficient over long periods of time..

What is the functional unit of a skeletal muscle called quizlet?

The myofibrils are composed of actin and myosin filaments, repeated in units called sarcomeres, which are the basic functional units of the muscle fiber. The sarcomere is responsible for the striated appearance of skeletal muscle, and forms the basic machinery necessary for muscle contraction.
