Congenital dermal sinus It ensures that neurological condition does not degrade and prevents infection. Diagnosis can be confirmed through the use of advanced neuroimaging to observe the tract and associated lesions. During normal development, cutaneous ectoderm separates from neuroectoderm to allow for the insertion of mesoderm. That is, the skin separates from the tissue of the spinal cord to allow proper formation of the vertebral column. In cases of congenital dermal sinus there is a failure in this process, resulting in formation of a persistent connection between the skin and neural tissue. This manifests as a tract extending from the surface of the
Female body shape have been exactly identical to the Vitruvian Man because the human body is always changing to adapt its environment. "In the more than five centuries since, human height has changed." In fact, when Da Vinci was drawing this figure in the 15th century, the average height of men of European ancestry was 5'6"–5'8"; however the average male height today is 5'9"–5'11". Kilgore ends his experiment stating that the Vitruvian Man does not accurately describe the modern male or female. In another social experiment, researchers Kara Crossley, Piers L. Cornelissen, and Martin Tovée explore what an attractive body is, asking multiple
