  The figures I’m looking at call the dorsal plane “frontal” which at last makes sense. Dorsal and ventral would be their regular directions in the frontal plane. I’m a brain guy so I normally only deal with the things in the neuraxis.

    It can be either the frontal or dorsal, however consider in zoology “dorsal fin”. Intuitively this is because the front of these animals doesn’t align with the frontal plane as it does in humans, but dorsal is a common alternative.

      Dorsal plane still doesn’t make sense to me as dorsal/ventral are the directions in the plane. In the same way it wouldn’t make sense to describe something as the lateral plane if the directions are medial/lateral. But as I said I’m a brain guy.

        Dorsal means towards the (anatomical) back, ventral means towards the ground. These are perpendicular to the dorsal plane, as frontwards is perpendicular to the frontal plane.

        I’m unfamiliar with brain orientation so perhaps the tradition is a bit different!
