1. 6 Branchial Arches:: 1st arch: mandibular arch (Meckel cartilage)
2nd arch: hyoid arch (Reichert cartilage)
3rd-6th arches: responsible for development of structures in the neck
2. Two separate embryonic palate structures:: - primary palate (anterior one-third)
- secondary palate (posterior two-thirds)
3. Primary palate forms to what?: Intermaxillary segment
4. 3 consecutive stages of palate:: - formation of primary palate
- formation of secondary palate
- formation of complete palate
5. Formation of complete palate is:: different surface fusion of all three processes
6. Development of primary palate:: Medial nasal process -> intermaxillary segment -> primary palate
-> premaxilla
7. Development of secondary palate:: fusion of palatal shelves
8. Palatal shelves:: "zipper" that brings palatal shelves together all the way to soft palate and uvula forms by
the maxillary process
9. What teeth does secondary palate form?: maxillary canines and posterior teeth
10. What is the secondary palate responsible for?: Complete separation between nasal cavity
and oral cavity and becomes separate space for oral cavity and two separate spaces for nasal cavity due to formation
of nasal septum and palatal shelves forming together (tongue is pulled down to floor of the mouth to allow fusion)
11. Development of complete/final palate:: The three processes fuse together to form final palate,
including the hard and soft palate
12. Clinical consideration for palatal development:: - cleft palate
- cleft uvula
- epstein pearl
13. Cleft palate: failure of fusion of the palatal shelves with the primary palate and/or with each other
14. Cleft uvula: failure of fusion of the palatal shelves; "zipper" didn't make it all the way back
15. Epstein pearl: small white papule seen in the midline of the palate, represents epithelial tissue that
becomes trapped during the palatal fusion (congenital)
16. Development of nasal cavity and septum:: develops from median nasal processes
Vertical nasal septum fuses with the horizontally oriented final palate after it's formed
17. Clinical consideration for nasal cavity and associated tissue:: Deviated septum
