Embryo 51 Day Old with Translucent Skin
Computer Generated Image from Micro-MRI, actual size of embryo = 18.0 mm - This image provides a left-sided view of the embryo undergoing its eighth week of development. The age is calculated from the day of fertilization. The image has been manipulated so that the skin appears translucent so that the internal organs can be observed. The embryo still maintains a semblance of a curvature with the head bent downwards, but due to the strengthening neck muscles, the curve has decreased. The brain is highlighted orange. The large red structure in the trunk of the embryo is the liver. The red, tube-like structure protruding outwards from the embryo is the umbilical cord, a which serves as a mechanism for gas exchange, nutrient delivery and waste removal. Outlined in yellow are the arms and legs which have elongated. The hand plates have undergone distinction earlier than foot plates.
