Thick Filaments and its purpose. Thick filaments in a muscle fiber are made of many molecules of the protein myosin. Each myosin molecule has a fibrous tail region and a globular head. For clarity, only one head is shown here. Thin filaments are twisted chains made of the globular protein actin.
Thick filaments contain myosin, while thin filaments contain actin. Actin and myosin collectively are referred to as the contractile proteins, which cause muscle shortening when they interact with each other.hick filaments contain myosin, while thin filaments contain actin.
