Midlinedorsal
Midlinedorsal is an anatomical descriptor used in biology to indicate a feature located along the dorsal midline—the center line of the back or upper surface of an organism. The term combines midline (the line dividing left and right) and dorsal (the back side). In descriptive morphology, midlinedorsal describes lines, stripes, crests, sutures, or color patterns that run along the center of the dorsum from head to tail. It is commonly applied in ichthyology (fish), herpetology (reptiles and amphibians), and entomology, and can also appear in paleontological descriptions of fossil vertebrates.
A midlinedorsal feature is defined by its position rather than its composition. Examples include a midline
In practice, midlinedorsal is relative to the observer's orientation, and when used in clinical or anatomical
