Answer:
back
Step-by-step explanation:
The root word dorso means back
The concept of dorsal comes from the Latin word dorsuālis. It is about that linked to the back or the back. For example: "The child was born with a defect in the spine," "This species is characterized by the size of its dorsal fin," "I have had severe pain in the dorsal area for several days."
In the field of anatomy, the structure behind the frontal plane is described as dorsal. The dorsal region, therefore, is the one that is left behind if an imaginary division of the body is done in half in a vertical direction, advancing perpendicular to the ground (in the case of the bipeds), or that is further from the surface if the body is divided in half horizontally with an imaginary cut parallel to the ground (in the case of quadrupeds).
The spine, also called the spine, is the structure that extends from the pelvis to the head, through the back and neck. It protects the spinal cord, provides support to the skull and allows the human being to stay upright and move in a bipedal manner.
