  1. Notocord
    • The Longitudinal, flexible rod located between digestive tube and nerve cord.
    • Gives Skeletal Support
  2. Dorsal Hollow Nerve Cord
    • Develops into central nervous system
    • Develops from ectoderm
  3. Pharynegeal Gill Slits
    Allows water to exit the mouth without going through the digestive tract
  4. Amniotic Egg
    Allow life cycle to be completed entirely on land. Self-sufficient.

  9. Eutherians
    Mammals that have longer gestation periods with complex placentas.
  10. Neural Tube
    Embryo's undeveloped central nervous system.
  11. Neural Crest Cells
    Contribute to formation of several human structures (i.e. teeth, sense organs etc.).
  12. Cephalization
    Concentration of sensory and neural equipment in the head.
  13. Spiral Valve
    Structure in intestines of Gnathostomes to increase surface area and prolong passage of food along short digestive tract.
