Chapter 2. Prehension

Figure 2.5 Prehensile postures consist of combinations of three basic ways that the hand can
provide oppositions around objects. The solid line shows the opposition vector seen in the object.
The shaded area represents the plane of the palm. Note the orientation of the opposition vector
relative to the plane of the palm. A. Pad opposition occurs along an axis generally parallel to the
palm, B. Palm opposition occurs along an axis generally perpendicular to the palm, and C. Side
opposition occurs along an axis generally transverse to the palm.
