actually myosin is also called the thick filament.....
Individual muscle fibers are formed during development from the fusion of several undifferentiated immature cells known as myoblasts into long, cylindrical, multi-nucleated cells. Differentiation into this state is primarily completed before birth with the cells continuing to grow in size thereafter. Skeletal muscle exhibits a distinctive banding pattern when viewed under the microscope due to the arrangement of cytoskeletal elements in the cytoplasm of the muscle fibers. The principal cytoplasmic proteins are myosin and actin (also known as "thick" and "thin" filaments, respectively) which are arranged in a repeating unit called a sarcomere. The interaction of myosin and actin is responsible for muscle contraction.

What are the thick protein filaments in the cell made of?
The thick filament is composed of the myosin molecule. The thin filament is composed of the actin molecule. Flexing the head of myosin provides the powerstroke.
What do sarcomere contain?
Sarcomeres are composed of actin (thin filaments) and myosin (thick filaments).
What is composed of myosin?
Thick Filaments
Thick protein filaments within the A-bands?
Myosin. The A band has thick (myosin) and thin (actin) filaments.
What is composed of myosin protein?
thick filaments
The thick filaments of muscle fibers are composed of what?
Myosin

What do sarcomere contain?
Sarcomeres are composed of actin (thin filaments) and myosin (thick filaments).
What are thick myofilaments of muscles called?
Actin. Myosin are the thin ones.... it's actually the reverseThe thin filaments are composed primarily by the protein Actin.The thick filaments are composed primarily of the protein Myosin.
What is composed of myosin?
Thick Filaments
Thick protein filaments within the A-bands?
Myosin. The A band has thick (myosin) and thin (actin) filaments.
What protein makes up the thick filaments of myofibrils?
Myosin makes up the THICK filaments, and actin makes up the thin filaments of myofibrils.
Which of the following become connected by myosin cross-bridges during muscle contraction A) thin filaments and thick filaments B) thin filaments and t-tubules C) thick filaments and titin filame?
Interactions between actin and myosin filaments of the sarcomere are responsible for muscle contractions. The I bands contain only thin (actin) filaments, whereas the A bands contain thick (myosin) filaments.
What is composed of myosin protein?
thick filaments
What are the types of proteins contained in myofibrils?
In the thin filaments of miofibrils, actin is the primary protein. In the thick filaments, myosin is the primary protein.Troponin, Tropomyosin, myosin.
What makes up a myofibril?
Myofibrils are made up of actin (thin filaments) and myosin (thick filaments).
What are two myofilaments that slide past one another to allow muscle cells to contract?
Actin and Myosin
