Usage: biology; anatomy; technical

Examples

• The dorsoventrality of vertebrates is evident in the positioning of the spine along the back and the ventral placement of internal organs.
• Fish exhibit clear dorsoventrality, with darker pigmentation on the dorsal surface and lighter coloring on the ventral side.
• Embryologists study dorsoventrality to understand how organisms develop distinct upper and lower body regions.
• The dorsoventrality of insects allows them to have a hardened dorsal exoskeleton and a softer ventral surface.
• Amphibians demonstrate dorsoventrality through the arrangement of their skeletal and muscular systems.
