Question

Quizplus · Accepted Answer

Sarcomeres are the units of contraction in a muscle. They are composed of thin and thick filaments, arranged in a specific pattern that allows for muscle contraction. Myofilaments and Z lines are components of the sarcomere, but they are not the units of contraction. Sarcolemmas are the membranes that surround muscle fibers, but they are not directly involved in muscle contraction.
