Wood in the form of broad, thin, flat or sometimes curved pieces that serve as a support for media in visual works; examples are paintings on wood. In architecture and other constructive arts, use "panels (surface components" to refer to a panel, whether of wood or another material, that is typically a compartment of a surface either sunken below or raised above the general level, and set in a molding or other border, as in a frame, sometimes of different color or material.
