During contraction, thin ________________ filaments slide past the thick ______________ filaments which result to shortening of sarcomere and contraction of the muscle.

Question

Quizplus · Accepted Answer

The sarcomere is made up of thin filament (actin) and thick filament (myosin) which slide past each other during contraction. Troponin and tropomyosin are both regulatory proteins that regulate contraction and relaxation of skeletal muscle.
Please see the diagram below as a visual reference for the anatomy of a sarcomere referenced in the question above.
