Embryonic development,computer artwork. This shows the process of gastrulation,where cells at one position on the embryo create a groove (blastopore,bottom right in diagram 2) and migrate into the centre. The cells then differentiate into the 3 germ layers; the ectoderm (yellow),endoderm (red) and mesoderm (green). The ectoderm forms epidermis and nervous tissue,the endoderm forms the digestive tract,glands and lungs and the mesoderm forms the connective tissue,including blood vessels and cartilage | |
