The smaller fiber in a muscle fiber is called a myofibril. A band of tissue that connects bone to bone is called a ligament.

Muscles that are better at providing long term physical activity
A twitch is the rapid rise and fall in force produced by a muscle fiber after a single action potential.
A single muscle cell is called a muscle fiber.
just take a guess of what it is.
Muscle cells are called muscle fibers because of their long, slender shape that resembles a fiber. The structure of muscle cells allows them to contract and generate force, which is essential for muscle function. The term "fiber" is used to describe the long, cylindrical shape of these cells that run parallel to each other in muscle tissue.

It is not the muscle but the muscle fiber which works for when recruited for long duration. The red muscle fiber or the slow twitch fiber gets recruited for long term stress on the muscle for example if you do bench press on heavy weight explosively for 5 reps you extensively use fast twitch fibers but if you do bench flys for 15 reps in controlled fashion, you extensively use red fibers.

The sacromere with the proteins actin and myosin allow the muscle cell (fiber) to contract.
