Muscular System STRUCTURE

Front

What is the Z disc?

Back

The midline of the I band that tether the thin filaments.

Front

From smallest to largest, which list of muscle components is in the correct order?

Back

Myofilaments, Muscle Fiber, Fascicle, Muscle Tissue.

Front

What are thick filaments?

Back

Myosin.

Front

Which type of muscle is under our conscious/voluntary control?

Back

Skeletal Muscle.

Front

What is the main function of skeletal muscle?

Back

Attached to bones and help with movement.

Front

What are myofilaments?

Back

The filaments of myofibrils, constructed from proteins, primarily actin and myosin.

Front

What is the function of actin in muscle contraction?

Back

Actin is a thin filament that interacts with myosin to facilitate muscle contraction.

Front

What is the role of myosin in muscle contraction?

Back

Myosin is a thick filament that pulls on actin to cause muscle contraction.

Front

What is a fascicle?

Back

A bundle of skeletal muscle fibers surrounded by perimysium.

Front

What is muscle tissue?

Back

A group of muscle cells that work together to produce movement.
