Which of the following become connected by myosin cross-bridges during muscle contraction?

Question

Quizplus · Accepted Answer

During muscle contraction, myosin cross-bridges from thick filaments attach to the thin filaments and pull them towards the center of the sarcomere, resulting in the contraction of the muscle fiber. Titin filaments provide structural support to the sarcomere, Z disks anchor the thin filaments, and T tubules play a role in transmitting the electrical signal for muscle contraction but do not become directly connected by myosin cross-bridges.
