Best Answer

The two filaments involved are myosin and actin.

Actin: is the framework and slides over the myosin filament when the muscle is shortened.

myosin: is a thick filament

Also a sacromere: is made up of the actin and myosin. It is the functional unit of a muscle fibre and extends from z line to z line.

A muscle contraction: is many sacromeres shortening ( actin sliding over myosin)

Actin and myosin. Actin is the thin filament and myosin is the thick filament that contains the heads.
