What is the first phase after a stimulus in a muscle contraction?
Latent Phase
Do all cardiac muscle fibers all contract at the same time?
No. The heart muscle contracts in sections, first the top (atrium) then the bottom (ventricle). But when it is working properly, the heart muscle fibers contract together in large groups.
What result would be expected if an additional stimulus equal in intensity to the first were applied to the muscle at the 60 millisecond time point?
the muscle would increase in tension to a level greater than that measured at the beginning of phase C.
What works in pairs to pull your your bones in different directions?
They are the muscles. Muscles contract in pairs to move the parts across the joint. One muscle contract with more power. The opposite muscle contracts with less power and get stretched over to allow the first muscle to act.

What burns first fat or muscle?

Why is treppe an important phenomenon for athletes to be aware of?
The concept or phenomenon of "Treppe" occurs when a muscle contracts more forcefully after it has contracted a few times than when it first contracts. This is due to the fact that active muscles require decreasing degrees of succeeding stimuli to elicit maximal contractions. Returning to our example of the second set of squats feeling easier than the first, during the first set there was insufficient warm-up, and the second set felt easier because the first set actually served as a warm-up. The phenomenon in which the contraction strength of a muscle increases, due to increased Ca2+ availability and enzyme efficiency during the warm-up.
