Human body bilateral symmetry

The bilateral symmetry of the human body is emphasized by the static character of many Egyptian sculptures (Figure 2-1). Mobility and dynamism, however, do not diminish the impression of bilateralness of the human body (Figure 2-2).

The bodies of most animals are bilaterally symmetrical, a form in which a plane could pass through the animal only in one place to divide it into two equal parts. The two halves of a bilaterally symmetrical animal are mirror images of each other. Bilateral symmetry is associated with animals that move around. The leading part of a bilaterally symmetrical animal s body contains sense organs such as eyes and nose. Fish, whales, birds, snakes, and humans are all bilaterally symmetrical.
