Explanation:
Detailed explanation-1: -The bundles of myofilaments are called myofibrils. The structure of the sarcomere is traditionally described with dark and light bands visible under the microscope. This banding pattern in sarcomeres is due mainly to the arrangement of thick and thin myofilaments in each unit.
Detailed explanation-2: -Actin filaments, the thin filaments, are the major component of the I-band and extend into the A-band. Myosin filaments, the thick filaments, are bipolar and extend throughout the A-band. More items
