Which of the following tissue includes elongated cells also known as muscle fibers?

Muscular tissue is made up of elongated cells known as muscle fibers. These fibers are specialized for contraction, which allows for the movement of the body and its parts. 

Muscular tissue can be further classified into three types: skeletal muscle, smooth muscle, and cardiac muscle. 

Skeletal muscles are attached to bones and are responsible for voluntary movements, while smooth and cardiac muscles are found in organs and blood vessels and are responsible for involuntary movements.
