Question

Quizplus · Accepted Answer

The mesoderm is the primary germ layer that gives rise to the serous membranes of the peritoneum, including the visceral and parietal peritoneum. The ectoderm forms the nervous system and epidermis, while the endoderm gives rise to the lining of the digestive and respiratory systems. The neural crest gives rise to various tissues including the teeth, sensory ganglia, and adrenal glands, but not the peritoneum.
