The heavy chains form fibrous, rigid ‘coiled coils’ in what are known as the tail and neck regions and then split into globular heads, on to which the light chains are attached.

WebThe heavy chains have a shape similar to a golf club, having a long shaft-like structure, to which is connected the globular myosin head. The shafts, or tails, wrap around each other and interact with the tails of other myosin molecules, forming the shaft of the thick filament. The globular heads project out at right angles to the shaft.
