DEVELOPMENT OF PALATE
The development of palate is significant process that involves the coordinated growth
and fusion of several tissue layers and structures during embryonic development.
The palate forms from the fusion of two main parts and these are; primary palate and
secondary palate.
The primary palate forms from medial aspect of nasal cavity and it gives rise to the
upper jaw and nose.
The secondary palate forms from lateral aspect nasal cavity and gives rise to the hard
and soft palate.
STAGES IN PALATE DEVELOPMENT
1. WEEK 5- 6 the primary palate forms from medial nasal prominence.
2. WEEK 7-8 the secondary palate forms from lateral nasal prominence.
3. WEEK 9-10 the secondary palate grows and elevates fusing with primary
palate.
4. WEEK 11-12 the palate shelves fuse forming the hard palate.
5. WEEK 13-14 the soft palate forms from the posterior of the secondary palate.
ASPECT OF PALATE DEVELOPMENT
1. Shelf formation, the secondary palate forms as the shelves that grows
inwards from the lateral nasal wall, shelves fuse to form the hard palate
2. Elevation and fusion, the palate shelves elevate and fuse forming a hard
palate
3. Muscle attachment, soft palate develops from posterior portion of
secondary palate and attaches to muscle like tensor velli palatini.
4. Neural crest cell migration, neural crest cell migrate to form palates
connective tissue, bone and cartilage
