Answer :

A muscle cell's fundamental rod-shaped organelle is called a myofibril. They are made of several chains of myofibrils that are long, tubular cells known as muscle fibres.

What is myofibril and its function?

Sarcomeres, a muscle's functional units, make up myofibrils. The sliding-filament concept is used by the myofibril to produce muscle contraction. When tendons are at rest, the dense and thin filaments do not completely overlap, with certain regions having neither of the two types.

What are myofibrils are composed of?

The dense and thin myofilaments that make up the myofibrils are what give the muscle its rough appearance. Also with two other muscle regulating proteins, tropomyosin and troponin, the thick filaments are made up of strands of the protein myosin, while the thin filaments are made up of strands of the protein actin.
