From which embryonic germ layer does the pancreas develop?
Solution
Correct Answer: Option C
- The pancreas develops from the endoderm, which is one of the three primary embryonic germ layers.
- During embryogenesis, the endoderm gives rise to the epithelial lining of the gastrointestinal tract and associated organs, including the liver, lungs, and pancreas. Specifically, the pancreas forms from the foregut endoderm as dorsal and ventral pancreatic buds, which later fuse to constitute the mature pancreas.
- In contrast, the mesoderm primarily forms muscles, bones, and the cardiovascular system; the ectoderm gives rise to the nervous system and skin; and neural crest cells contribute to peripheral nervous structures but not to the pancreatic tissue.
Therefore, the correct answer is endoderm because it is responsible for the development of the pancreas as part of the digestive system.
