The ventral epidermis is lined with multi-ciliated cells responsible for gliding motility, while the more densely packed dorsal surface contains many non-ciliated and mucous-secreting, rhabdite-containing cells (Pedersen, 1976).
Another advance was the ceramic discs, which are baked at 2,700 degrees until hardened, but whose surface contains tiny pores that allow coral larvae to take root.
If the fruit's surface contains infectious organisms, they can spread to its flesh when the fruit is cut.

In one place the surface contains a bump, which is visible from the perspective of a larger three-dimensional space in which the surface is contained.
Radium thus occurs in all uranium ores, but it is more widely distributed because it forms water-soluble compounds; Earth's surface contains an estimated 1.8 × 1013 grams (2 × 107 tons) of radium.
Its surface contains two different kinds of titanium atoms.
The glass table surface contains a special solar cell which creates an electrical current.
This implies that the surface contains spatial frequencies greater than one cycle per two control points.
