Answer 13

palatine raphe

Question 14

What is the palatine raphe?

Answer 14

fusion of palatal shelves

Question 15

Why do cleft palates occur?

Answer 15

Failure of lateral palatine processes to meet and fuse, raphe doesn’t zip together

Answer 29

stops food entering the nose during swallowing

directs air into the nose or the mouth during speech, sneezing, coughing & vomiting

helps to close off the entrance into the oropharynx during the gag reflex
