What else can I help you with?
What type of muscle is capable of rapid contraction and causes skeletal movement?
Skeletal or voluntary muscle is capable of rapid contraction and is responsible for skeletal movement.
What factors affect muscle contraction?
the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
True or false When the contraction of a skeletal muscle is studied in the laboratory by applying an electrical charge to the muscle the contraction is called a muscle twitch.?
true
Organelle storing calicium in resting skeletal muscle fibers?
The organelle responsible for storing calcium in resting skeletal muscle fibers is the sarcoplasmic reticulum (SR). It releases calcium ions when muscle contraction is initiated by a nerve impulse. Calcium is essential for muscle contraction as it acts as a trigger for muscle fiber activation.
The structure storing calcium in the skeletal muscle fibers at rest is the?
The structure responsible for storing calcium in skeletal muscle fibers at rest is the sarcoplasmic reticulum. This organelle regulates the release of calcium ions during muscle contraction to trigger the muscle fiber to contract.
What happens to the strength of contraction during wave summation?
It increases about to about four times greater than a normal contraction for skeletal muscle.
What band shortens during skeletal muscle contraction?
during skeletal muscle contraction ,I band and H zone shortens. Sarcomeres
In addition to myosin what other protein is involved in skeletal muscle contraction?
Myosin acts with Actin during muscle contraction
How does the contraction of the I band contribute to the overall function of skeletal muscle?
The contraction of the I band in skeletal muscle helps to shorten the muscle fibers, allowing for movement and muscle contraction. This contributes to the overall function of skeletal muscle by enabling the muscle to generate force and produce movement.
What type of muscle is capable of rapid contraction and causes skeletal movement?
Skeletal or voluntary muscle is capable of rapid contraction and is responsible for skeletal movement.
What other protein is involved in skeletal muscle contraction?
Troponin is another protein involved in skeletal muscle contraction. It works in conjunction with tropomyosin to regulate the interaction between actin and myosin filaments during muscle contraction.
Does stretch have any effect on skeletal muscle contraction?
yes skeletal muscle stretch by means of contraction.
Can skeletal muscle contract without shortening?
Yes. One possibility is that the load on the muscle exceeds the tension produced by the muscle so that the muscle actually lengthens during contraction (eccentric contraction).
The first step toward generating a skeletal muscle contraction is The first step toward generating a skeletal muscle contraction is?
stimulation of the muscle by a nerve ending.
What factors affect muscle contraction?
the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
What happens to the Z line during muscle contraction?
During muscle contraction, the Z line moves closer together, causing the muscle to shorten and generate force.
What happens to a muscle contraction if there is an excess amount of either Ca2 plus or ATP present during the contraction?
During muscle contraction the actin heads pull the sarcomere closed
