Dorsum (anatomy)

For portion of the brain sometimes called the dorsal, see Medial longitudinal fasciculus.

In 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 lepidoptera (moths and butterflies), the dorsum also refers to the trailing edge of the wing (the leading edge is called the costa).

Human neuroanatomy

In the forebrain region in humans the term "dorsal" is used equivalently to "superior" (towards the top of the head).^[1]

Nerve rootlets stemming from the spinal cord form dorsal (sensory) and ventral (motor) roots before these unite to form the spinal nerve.
