Muscles and Other Actin-Myosin Contractile Systems

> Actin and Myosin

> > Actin (Figure 8.1)

> > Myosin (Figure 8.3, Figure 6.11, Figure 8.4)

> > The Reaction of Myosin and Actin

> The Structure of Muscle (Figure 8.8, Figure 8.9a)

> The Mechanism of Contraction: Sliding Filament Model (Figure 8.10, Figure 8.11)

> Stimulation of Contraction: The Role of Calcium (Figure 8.13, Figure 8.14, Figure 8.15)

> Energetics and Energy Supplies in Muscle (Table 8.1, Figure 8.12, Here, Figure 12.14)

> Nonmuscle Actin and Myosin (Figure 8.17)
