The 72-hr Chick Embryo Whole Mount (SEE IMAGE) Again, before mounting your slide on the microscope stage, take a good look at the whole mount of the 72-hour chick embryo. Observe the tail fold of the amnion. Try to identify the structures that you had seen in the 33-hour and 48-hour chick embryos. Just like in the whole embryos of the 33- and 48-hour chick, you shall be making frequent reference to the whole mount of the 72-hour embryo to aid you in understanding the plane of sectioning and therefore the structures that you will expect to see in the sections. QUESTIONS: What changes in the morphology and gross anatomy are noticeable? How far back has the amnion closed? Have the head fold and tail fold fused to form the amniotic cavity? YES or NO? Why?
