- Dorsum (biology)
anatomy, the dorsum is the upper side of animals that typically run, fly, or swim in a horizontal position, and the back side of animals (like humans) that walk upright. In vertebrates the dorsum contains the backbone. The term dorsal refers to anatomical structures that are either situated toward or grow off that side of an animal. The opposite side of the animal is described with the terms ventrum and ventral.
In humans, the top of the foot is considered dorsal. It contains small extensor muscles and extensor tendons from the
leg. It is supplied by the deep peroneal nerve.
Examples of anatomical terms that include "dorsal" are the
dorsal finof fish, dorsal root ganglion, dorsal root, dorsal nerve, dorsum sellae, dorsal arch, dorsalis pedis artery, dorsal ramus, dorsal scales of snakes, dorsal respiratory group, dorsal venous arch, and dorsiflexionamong others.
lepidoptera, the dorsum also refers to the trailing edge of the wing (the leading edge is called the costa).
neuroanatomy, once you reach the forebrain, dorsal is equivalent to superiorand ventral is equivalent to inferior. [Young and Young: [http://www.amazon.com/dp/0683093517 Basic Clinical Neuroanatomy] ]
