Which Statement Concerning the Length-Tension Relationship of Skeletal Muscle Is

Question 265

Multiple Choice

Which statement concerning the length-tension relationship of skeletal muscle is INCORRECT?


A) When a muscle is maximally stretched, it can develop the most tension upon contraction because the thin filaments can slide a maximal distance.
B) Maximum tension can be developed if the muscle is at its lowest at the onset of contraction.
C) In the body, the relaxed length of muscle is at its optimal length.
D) When the initial length of muscle prior to contraction becomes very short, tension is decreased during contraction because of thin filament overlap, because the thick filaments are compressed against the Z lines, and because not as much Ca2+is released during excitation-contraction coupling.
