Primary Myofilament Composition:
- Primary myofilaments consist of two proteins, actin, and myosin.
- Actin is a thin filament while myosin is a thick filament.
- These two proteins work together to produce muscle contractions.

Function of Primary Myofilament:
- Primary myofilaments are essential for muscle contraction.
- During contraction, myosin heads attach to actin filaments and pull them towards the center of the sarcomere, resulting in muscle shortening.

Differences between Primary and Secondary Myofilament:
- Primary myofilaments are not more than secondary myofilaments.
- Secondary myofilaments are made up of proteins like tropomyosin and troponin, which regulate the interaction between actin and myosin.

Structure of Primary Myofilament:
- Primary myofilaments have a striated appearance due to the arrangement of actin and myosin filaments.
- The surface of primary myofilaments is not smooth but rather has a repeating pattern of light and dark bands known as striations.
In conclusion, primary myofilaments are composed of actin and myosin proteins that are crucial for muscle contraction. They work together to generate the force required for muscle movement and are organized in a striated pattern within the sarcomere.
