Formation of the Face |
(1) growth and migration of FNP, MaxP, and MandP (2) Differentiation of FNP to nasal placodes to nasal prominence (medial and lateral) forming the nasolacrimal groove (3) migration of nasalP to midline (4) fusion of medial nasalP with each other and fusion of medial and lateral nasalP with maxP |
|
|
Mandibular prominence gives rise to: |
lower jaw |
|
|
Maxillary prominence gives rise to: |
sides of face, lateral palatal shelves, upper lip |
|
|
FNP gives rise to: |
lateral nasalP, medial nasalP (intermax segment [philtrum, primary palate], nasal septum) |
|
|
Formation of the secondary palate |
From MaxP lateral palatal shelves growth towards midline after tongue descends Nasal septum from MaxP medial nasalP with down growth from roof to fuse with lateral palatal shelves of MaxP |
|
|
Primary palate arises from: |
intermaxillary segment of FNP (medial nasalP) |
|
|
Where primary and lateral palatal processes meet: |
incisive foramen |
|
|
Differentiation of nasal placodes |
nasal placodes to nasal pits to nasal sacs |
|
|
Definitive choana forms after: |
