Here are a few simple Quiz questions that relate to Early Embryo from the lecture and practical.

  

1 Which of the following best describes the term "ectomesenchyme":

ectoderm derived from mesoderm
epithelium derived from connective tissue
sensory placodal induction by mesoderm
connective tissue derived from neural crest
none of the above is correct

2 Abnormal or perturbed migration of neural crest cells may result in malformation of structures derived from the:
