**Educational Content: Neural Crest Cell Migration**

**Question: True Statements Regarding Neural Crest Cell Migration (Select all that apply):**

- **A**: A defect in the migration of cranial neural crest cells would impair the development of the skull.

- **B**: Chemoattraction causes neural crest cells to migrate as a sheet with placodal cells.

- **C**: Facial skeletogenic neural crest contributes to the development of the forebrain by secreting Noggin.

- **D**: Cardiac neural crest cells only contribute to the formation of the cardiac outflow tracts.

- **E**: A defect in cardiac neural crest cell migration would impair the formation of the aortic-pulmonary septum.

- **F**: A migrating neural crest cell is polarized with active Rac1 at the rear and active RhoA in the migration front.

- **G**: The border between the neural crest and the neural plate is established by the antagonism between Snail2 and Sox2.

- **H**: The ventrally migrating trunk neural crest cells are attracted by Ephrin to the posterior sclerotome.

- **I**: Cranial neural crest that migrates from rhombomeres 3 and 5 do not form any adult derivative.

- **J**: Vagal and sacral neural crest cells mostly contribute to the sympathetic ganglia of the gut.

**Note**: This is a multiple-choice question where students must select all true statements related to the roles and migration patterns of neural crest cells in embryonic development.
