Example Question #1 : Help With Gastrulation And Embryonic Structures
Which germ layer will develop into the skeletal and muscular systems?
The skeletal and muscular systems do not arise from the same germ layer
Following gastrulation, three primary germ layers form: the ectoderm, the mesoderm, and the endoderm. We can typically predict which structures will form from the germ layers based on the layers of the body. The endoderm will form the digestive tract, the mesoderm will form the skeleton and muscles, and the ectoderm will form the skin and nervous system.
