Skeletal muscle twitch differs from a tetanic contraction in that?
Skeletal muscle twitch is a single, brief contraction and relaxation cycle, whereas a tetanic contraction involves sustained, rapid repeated contractions without relaxation in between. Tetanic contractions occur when the muscle is stimulated at a high frequency, leading to a fused contraction.
In an isotonic contraction the muscle does what?
In an isotonic contraction, the muscle changes in length while maintaining a constant tension. This allows for movement to occur, such as bending the elbow or lifting a weight.
What chemical reactions occur in the muscle during latent period of muscle contraction?
During the latent period of muscle contraction Ca++ is being released from the sacroplasmic reticulum and filament movement is taking up slack. This takes approx. 2 milliseconds.
Constant contraction of a muscle is?
constant contraction of a muscle is called the muscle tone
Are ATP and calcium both needed for muscle contraction to occur?
look in ur freaken book loser.
Would extending be an isotonic contraction?
No, extending a muscle is not considered an isotonic contraction. Isotonic contractions occur when a muscle changes length while maintaining a constant tension, such as during lifting or lowering a weight. In contrast, extending typically refers to the lengthening of a muscle under tension, which can occur during eccentric contractions, where the muscle lengthens while still generating force.
What is the medical term meaning delayed relaxation of a muscle after a strong contraction?
The medical term for delayed relaxation of a muscle after a strong contraction is myotonia. This condition is characterized by prolonged muscle stiffness or difficulty relaxing the muscle after it has been contracted. Myotonia can occur in conditions such as myotonic dystrophy or myotonia congenita.
What would occur if the uptake of calcium ions was blocked in the sarcoplasmic reticulum?
Blocking the uptake of calcium ions in the sarcoplasmic reticulum would prevent muscle contraction. Calcium ions are critical for the release of stored calcium, which activates the muscle contraction process. Without this calcium release, the muscle would not be able to contract effectively or at all.
What is muscle contraction without muscle shortening is what kind of contraction?
Isometric contraction. This type of contraction occurs when the muscle generates tension without changing its length, such as when holding a weight in a fixed position.
Describe the events of muscle cell contraction?
6 steps in a muscle contraction
What does the contraction of the gastrocnemius muscle usually result in?
type of contraction of gastrocnemius muscle?
What is the difference between isotonic and isometric contractions?
An Isotonic muscle contraction is a muscle contraction that makes your limbs move whereas an Isometric contraction is a muscle contraction where the limbs stay static
