Example Question #84 : Systems Physiology

Which germ layer will develop into the skeletal and muscular systems?

Possible Answers:

Epiderm

The skeletal and muscular systems do not arise from the same germ layer

Mesoderm

Ectoderm

Endoderm

Correct answer:

Mesoderm

Explanation:

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.
