What else can I help you with?
What chemicals are involved with contracting muscles?
Actin (thin myofilament), myosin (thick myofilament), calcium, and ATP (energy).
The protein that makes up the thin myofilament?
protein that makes up thin myofilament
What protein makes up the thick myofilament?
The protein that makes up the thick myofilament in muscle cells is called myosin. Myosin is a motor protein that plays a key role in muscle contraction by interacting with actin, the protein in the thin myofilament.
The thick filaments of muscle fibers are composed of what?
Myosin
What are birds wings made of?
thin bones, muscles and feathers
A muscle tissue made up of long thin cells?
A muscle is made up of many fasicles. These fasicles contain myofibrils. The myofibrils contain sarcomeres which contain myosin and actin filaments which is the molecular movement for muscle contraction.
Do myosin filaments outnumber actin filaments in skeletal muscles?
No, actin filaments outnumber myosin filaments in skeletal muscles. Actin filaments are thin filaments, while myosin filaments are thick filaments. The arrangement and interplay of these filaments during muscle contractions are essential for movement.
Can muscle cells form cardiac and skeletal muscles?
Skeletal muscle cells are much bigger than cardiac muscle cells. Skeletal muscle fibres are up to 100 micrometers in diameter and several centimeters long while cardiac myocytes are about 15 micrometers in diameter and about 100 micrometers long.
What is myofilament?
Myofilaments are the protein fibers within muscle cells that slide past each other to cause muscle contractions. There are two main types of myofilaments: thin filaments, made up of actin protein, and thick filaments, made up of myosin protein. The interaction between these two types of filaments is essential for muscle contraction.
What are the thin muscles found in your body?
What everyone calls the abs are thin muscles of the body.
What are the examples of thick and thin muscles?
muscles
Compare and contrast between skeletal muscles and smooth muscles?
Skeletal muscles look like long muscle fibers with a nuclei in each one, looks striated or striped. Compared to a smooth muscle that looks like sheets of thin cells each have a nucleus as well but looks smooth.
