Medical visualization taken from human scanned data showing an anterior and posterior view of an embryo at week 6 after fertilization. An inset is also shown that displays the somites (ridges on the tail that are the foundation of the skeletomuscular system) in more detail. In the front view, the head (top) can be seen bending downward. The tubelike form in the head is the neural tube, formed by the closing of the neural groove 28 days after fertilization. When the tube doesn't close completely, neural tube defects (NTDs) develop. NTDs are common birth defects, occurring in about 1 in 1, 000 live births. | |
