Myofibril

Basic rod-like unit of a muscle cell that is responsible for muscle contraction.

Myofilaments

The filaments of myofibrils, constructed from proteins, primarily actin and myosin, which are essential for muscle contraction.

Actin

A protein that plays a vital role in muscle contraction and cell movement.

Myosin

A type of protein found in muscle fibers that interacts with actin to convert chemical energy into mechanical energy, leading to muscle contraction.
