Actin is a microfilament, I thought it was a sacromere thin filament? and myosin was a sacromere thick filament?

Actin is the globular protein that makes up the microfilaments. Thin filaments are made up of actin as well. Mysoin is a thick filament but not composed of actin. It is part of its own protein family.

I understand that myosin and actin are two separate things. I always thought within the sacromere picture with the different bands, actin is counted as the sacromere thin filament and myosin is the thick filament. no?
