Answer:
Muscles at the microscopic level are made of actin (thin filament) and myosin (thick filament) fibers in alternation and parallel to each other.

Several actin and myosin fibers make up a myofibril. Each contractile unit in the myofibril is called a sarcomere – viewed as Z-discs at the microscopic level.
