Why are muscle tissue also known as muscle fibre?

Muscle tissue is often referred to as muscle fiber because it is composed of long, slender cells that resemble fibers. These muscle fibers are specialized for contraction and are responsible for producing movement in the body. The term "fiber" highlights their elongated structure and functional characteristics, distinguishing them from other types of cells in the body. Additionally, muscle fibers can vary in type, such as slow-twitch and fast-twitch, each adapted for different types of physical activity.
