Bios 325 33-Hour Chick Embryo Term List
Here is the list of terms you are responsible to identify. Remember that you not only need to identify them but know the characteristics such as origin and derivatives of each structure. Find each structure in whole mount and transverse (cross) sections and trace them from anterior to posterior sections to familiarize yourself with the structure at different levels of the embryo.
Whole mount:
1.area vasculosa
2.area pellucida
3.blood islands
4.vitelline veins
5.somites
6.neural tube
7.neural groove
8.neural folds
9.primitive ridges
10.primitive groove
11.primitive streak
12.optic vesicles
13.telencephalon + diencephalon = prosencephalon
14.mesencephalon
15.metencephalon + myelencephalon = rhombencepahlon
16.neuromeres
17.infundibulum
18.anterior (cranial) intestinal portal
19.heart
Serial sections:
1.telencephalon
2.diencephalon
3.mesencephalon
4.metencephalon
5.myelencephalon
6.optic vesicles
