Hand Function Muscles of the Wrist and Hand Length-tension relationships Extensor mechanism Control of the unloaded (free) hand Grips and Prehension Patterns Power grips Precision patterns Combined grips Table 19.1 outlines Muscles of the Wrist and Hand. Figure 19.2 illustrates the extrinsic and intrinsic muscles of the wrist and hand. Figure 19.3 illustrates anatomical structures of the extensor mechanism.
