Bio 204 Practice Final Exam
1. blastula formation: The morula becomes a blastula, a hollow ball of cells
2. cleavage: rapid division of cells forming a solid ball
3. gastrulation: archentron forms and blastocoel is displaced while the three germ layers differentiate
4. neurulation: formation of the neural chord and neural plate
5. dermis is made up of what tissue: deratome epimere mesoderm
6. appendicular skeleton origin: somatic hypomere mesoderm
7. kidney: mesomere mesoderm
8. epidermis: somatic ectoderm
9. CNS and eyes: Neural plate ectoderm
10. PNS and teeth: neural crest ectoderm
1/3
, 11. endoderm: bladder, lining of gi tract, liver, galblader, pancreas, trachea
12. mesenchymal cells: Stem cells that respond to injury or infection
Differentiate into fibroblasts, macrophages, etc.
13. splanchnic hypomere: heart, blood vessels, mesenteries that cover organs (dorsal and ventral mesen-
teries), interior
14. somatic hypomere: appendicular skeleton, peritoneum, gonads, exterior
15. coelom: body cavity lined with mesoderm
16. microlecithal: little yolk
17. birds cleavage: blastodisk (epiblast above, hypoblast below, blastocoel betwean)
18. somites from epimere mesoderm: myotome, deratome, schleratome
19. somatopleur: amnion+chorion
20. yolk sack+allantios: splanchnopleur
