Which cells have long fibers that can contract and relax?
Muscle cells can contract and relax and lave fibers as long as 1.5 feet.
What usually triggers muscle fibers to contract or relax?
The contraction is triggered by the release of calcium within the muscle which is triggered by an electrical signal from a nerve.
What is the organ system composed of tissue that can relax and contract?
The organ system composed of tissue that can contract and relax is muscle tissue.
What cells have fibers that can contract and relax?
Muscle fibres are a type of cell. They are found in bundles in muscles, surrounded by connective tissue, neurones and capillaries. Muscle fibres are long, multinucleated cells with a high tensile strength.
What muscle is slow to contract and relax?
cardiac
Can the heart tetanize?
The cardiac muscle fiber absolute refractory is a long period of time (longer then skeletal muscles), so you cannot tetanize cardiac muscle fibers because it has to relax before it is able to contract again.
What is The organ system composed of tissue that contract and relax?
The organ system composed of tissue that can contract and relax is muscle tissue.
What are the elements of muscle tissue that contract and relax and elongate?
Myofibrils
Which muscle type can voluntarily contract and relax?
Skeletal muscles .
Which cell in human body contract and relax?
Muscle cells
The ability of a muscle to contract and relax is dependent on the flow of what?
The ability of a muscle to contract and relax is dependent on the flow of calcium in and out of the muscle cell. Poor maternal intake of calcium increases the risk of hypertension in the adult offspring.
What are the only things a muscle can do?
A pull is the only action a muscle can perform.
