Based on Figure 34.7 and its accompanying text, which of the following statements about the neural crest is FALSE?

  • A: The neural crest cells originate near the margins of the embryonic folds that form the neural tube.
  • B: Neural crest cells are stationary and do not migrate once formed.
  • C: The migrating neural crest cells contribute to unique vertebrate anatomical structures like skull bones and cartilage.
  • D: The neural crest is depicted as bilateral bands of cells.

Explanation

Figure 34.7 b and its caption clearly state: 'Neural crest cells migrate to distant sites in the embryo,' directly contradicting option B, which claims they are stationary. Options A, C, and D are all accurate descriptions from the figure and text.
