What is the difference between Thick Filament and Thin Filament?

Thick Filament:

1. It is made up of protein myosin only.

2. It lies only in A-band.

3. It is bisected by a proteinaceous line called M-line.

Thin Filament:

1. It is made up of proteins - actin, tropomyosin and troponin.

2. It lies both in A and I band.

3. It is bisected by a proteinacious line called Z-line.
