VOLAR – used to describe the palm of the hand and the sole of the foot. Relating to or situated at or close to the back of the body or to the posterior part of an organ. In an animal that walks on all fours, the dorsal surface is its back. By extension, in all vertebrates it is the surface along which the spin runs. In animals that walk on two legs, such as humans, it is therefore the surface that faces backwards, or the posterior surface. In fish, the dorsal fin is the main fin running along the top of the body. See also surface anatomy.
