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

1

In human development, the first trimester is best described as:

  the period when organs begin to function
  the embryonic period and the beginning of the fetal period
  the least critical time of human development
  the beginning of fetal sensory function
  all of the above are correct

2

Which of the following answers describes the human embryonic period:

  the period before replacement of cartilage within the humerus by bone marrow begins
  a discrete entity that has not yet reached 8 weeks of development since the first mitotic division
  the developmental period up to 8 post-ovulatory weeks
  the period when more than 90% of the more than 4,500 named structures of the adult body have appeared
  all of the above are correct
