What is a myofibril?

A myofibril is a bundle of contractile filaments (myofilaments), 1-2 μm in diameter, that are arranged in parallel groups in the cytoplasm of striated muscle cells.


What contains a sarcolemma sarcoplasm myofilaments and myofibrils?

A muscle fiber contains a sarcolemma, sarcoplasm, myofilaments, and myofibrils. The sarcolemma is the cell membrane that surrounds the muscle fiber, while the sarcoplasm is the cytoplasm of the muscle cell, containing various organelles and substrates for energy production. Myofilaments, which are composed of actin and myosin, are organized into myofibrils that facilitate muscle contraction. Together, these components enable the muscle fiber to function effectively during contraction and relaxation.


What are the myofilaments called in a muscle cell?

The myofilaments in a muscle cell are called actin and myosin. Actin and myosin are protein filaments that work together during muscle contraction to generate force and movement.


What are Thick myofilaments are made of?

What is the ideal length?

minimal overlap of thin and thick myofilaments.


When muscles contract do the myofilaments themselves actually shrink?

the myofilaments themselves do not contract, they slide, this is called the Sliding Filament theory, in which the thick filament (Myosin) slides over the thin filament (Actin).
