Sarcomeres are composed of long, fibrous proteins as filaments that slide past each other when a musclecontracts or relaxes. ... Other bandsappear when the sarcomere is relaxed. A muscle fiber from a biceps musclemay contain 100,000 sarcomeres. The myofibrils of smooth muscle cells are not arranged into sarcomeres. Please mark as a brainlisy
