- stratified squamous

- first and second premolars
- central incisors
- lateral incisors and canine
- canine and first premolars - Correct Answer - c. lateral incisors and
canine A cleft of the alveolar ridge results from the lack of fusion of the premaxilla, which forms the anterior portion of the palate and gives rise to the maxillary incisors, and of the lateral palatine processes (palatal shelves), which give rise to the posterior two thirds of the hard palate and contain the maxillary canines and posterior teeth. The lines of fusion, therefore, fall between the laterals and the canine teeth.
