Dorsal
Dorsal (/ˈdɔːrsəl/), from the Latin dorsum meaning back, is a term used in anatomy to refer to the back or upper side of an organism or part of the body.
Etymology
The term dorsal is derived from the Latin word dorsum, which translates to "back". It is used in anatomical nomenclature to denote something as being towards the back side in humans and most other vertebrates.
Usage in Anatomy

For example, in the standard anatomical position, the most dorsal part of the hand is the back of the hand; the most dorsal part of the foot is the top of the foot.
