dorsoventral axis

The dorsoventral axis is an imaginary line that runs from the back (dorsal) to the front or belly (ventral) of an organism. It helps distinguish different parts of the body along this vertical plane. For example, in humans, the back is dorsal and the belly is ventral. This axis is fundamental in development and anatomy, guiding how tissues and organs form and positioning oneself within the body. Understanding this axis is key in studying anatomy, embryology, and the spatial arrangement of body parts across various species.
