What causes a cleft secondary palate?

Non-fusion of the palatine shelves with each other and nasal septum
Confusion of maxillary prominences with each other
Confusion of medial nasal prominences with lateral palatine processes
Non-fusion of the nasal septum with maxillary prominences

The correct answer is: Non-fusion of the palatine shelves with each other and nasal septum

A cleft secondary palate is caused by a non-fusion of the palatine shelves with each other and the nasal septum. This is an important step in fetal development, and if it does not occur properly, it can result in a cleft secondary palate. Option B is incorrect as it references maxillary prominences, which are not involved in the formation of the palate. Option C is incorrect as it combines two different facial prominences that are not directly involved in the formation of the secondary palate. Option D is incorrect as it references the nasal septum, which does not play a primary role in the formation of the secondary palate.
