Myofibril
Myofilaments Two types: actin (thin filament) & myosin (thick filament)
A myofibril is made up of repeating units called sarcomeres. Sarcomeres contain thick and thin filaments that slide past each other during muscle contraction. The protein fibers actin and myosin make up the thin and thick filaments, respectively.

Yes, a myofibril has a banded appearance. The sarcomere is delimited by two dark bands which are called the Z-discs. The Z-discs have two lighter colored bands and two darker bands.
