When viewing a 14-day old human embryo, could you identify the cranial and caudal ends? If yes, identify the structure(s) that would allow you to identify the cranial-caudal axis of the human embryo. If no, on what day would you be able to identify the cranial and caudal ends?
Discuss the development of the limbs. What primary germlayers form the limb bud? List the major events during eachweek of limb development.
