Definitions:

Sarcomere

The basic functional unit of striated muscle fibers, responsible for muscle contraction, delineated by Z lines.

Myosin Myofilaments

Myosin myofilaments are thick filaments found in muscle cells that, along with actin filaments, play a key role in the muscle contraction process by sliding past each other.

Z Disc

A specialized region within a muscle fiber's sarcomere that serves as the attachment point for actin filaments, marking the boundary between adjacent sarcomere units.

Anisotropic Band

A region within myofibrils of skeletal muscle cells that appears darker under a microscope due to the presence of thick myosin filaments.
