Hard palate and soft palate have substantial differences, although they may appear very similar to the eye. For example, the hard palate has a bony and periosteal component, of which the soft palate is completely devoid; on the other hand, the soft palate has 5 muscles, of which the hard palate is completely devoid.
From a functional point of view, the hard palate and the soft palate make a fundamental contribution to three processes: chewing, swallowing and phonation (ie the emission of words).
