What are the examples of thick and thin muscles?
muscles
Are there more thick filaments than thin filaments in smooth muscle?
There more thin filaments than thick filaments in smooth muscle. The ratio is of the thin to thick filaments in the smooth muscle is approximately 15:1.
What are examples of smooth muscles?
kidneys, stomach, intestines, bladder, the eyes, the walls of blood vessels. Smooth muscles that are sometimes called visceral muscles. They are thin muscles that look like spindles. They can be found in your skin and your blood vessels and your organs inside your body.
What are the thin muscles found in your body?

What is voluntary muscle?
Involuntary muscles are muscles that are not controllable consciously, and instead contract due to unconscious impulses sent by the autonomic nervous system or certain specialized cells or hormones. Both smooth muscle and cardiac muscle can be classified as involuntary muscles. Smooth muscle is comprised of spindle-shaped cells that have no striations and is found in numerous locations throughout the human body. Cardiac muscle is striated rather than smooth, and is found only within the walls of the heart. Smooth muscles are involuntary muscles composed of thick and thin protein filaments that are homologous to the organelles known as myofibrils found in skeletal muscles. The thin filaments are composed of a globular protein called actin, while the thick ones are made up of a motor protein called myosin. Smooth muscles require extracellular calcium ions to contract: the ions activate a nucleotide called Adenosine triphosphate (ATP), which then activates the myosin filaments. The myosin filaments attach to the actin filaments in a process known as the crossbridge cycle, which causes the thick and thin filaments to slide over each other and contract. When the myosin filaments release the actin filaments, the muscle relaxes.
What part of the body has thin muscles?

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 chemicals are involved with contracting muscles?
Actin (thin myofilament), myosin (thick myofilament), calcium, and ATP (energy).
What is the difference between thick and thin atmosphere?
A thin atmosphere is thin and a thick atmosphere is thick
What is the difference between a thin and thick atmosphere?
A thin atmosphere is thin and a thick atmosphere is thick
Why do skin cells heal fast?
Thick of it like this: all that protects your internal organs, muscles, and bones, is a thin layer of cells and hair. Skin has to heal fast in order to protect the inner body.
