What else can I help you with?
What is the time length for atrial diastole?
.7 seconds
The muscle decreases in muscle length during contraction but tension is the same?
Isotonic contraction
What is the formula for Lorentz contraction?
Lorentz contraction, or length contraction, coresponds to following formula: l = l0 * sqrt(1-V2/c2)
What is A contraction in which the muscle changes in length with the same tension applied to it?
Isotonic ContractionIsotonic Contraction
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.
What muscle contraction occurs in the biceps brachii during the upward phase of the bicep curl?
a concentric contraction- a concentric contraction involves the muscle length, shortening during a contraction! YA-trick-YA!
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.
Is length a constant?
No, length is a relative measure. If an object is travelling close to the speed of light it undergoes Lorenz contraction.
Walking is an example of which type of contraction?
Walking is an example of isotonic type of contraction. These are contractions which will force the length of the muscle to change and cause movement.
How does length contraction occur in relation to an object's motion, with the understanding that it only happens along a direction perpendicular to the object's motion?
Length contraction occurs when an object moves at high speeds, causing it to appear shorter in the direction of its motion. This contraction only happens along the direction of motion, not perpendicular to it.
The contractility of heart muscle is its?
contraction strength at any given fiber length
When the left ventricle contracts does the distance from the apex to the base increase or decrease?
When the left ventricle contracts, the distance from the apex to the base decreases. This contraction, known as systole, causes the ventricular walls to shorten and thicken, effectively reducing the overall length of the heart chamber. As a result, the apex moves closer to the base during this phase of the cardiac cycle.
