Question

how are actin and myosin arranged in a muscle fiber? ​

Answer 1

Explanation:

Each muscle fiber contains many myofibrils, which are bundles of actin and myosin filaments organized (more...) ... The myosin and actin filaments overlap in peripheral regions of the A band, whereas a middle region (called the H zone) contains only myosin.

Answer 2

Muscles are composed of two major protein filaments: a thick filament composed of the protein myosin and a thin filament composed of the protein actin. Muscle contraction occurs when these filaments slide over one another in a series of repetitive events.
