Innervated by facial nerve . </Li> <Li> Foliate papillae - these are ridges and grooves towards the posterior part of the tongue found at the lateral borders . Innervated by facial nerve (anterior papillae) and glossopharyngeal nerve (posterior papillae). </Li> <Li> Circumvallate papillae - there are only about 10 to 14 of these papillae on most people, and they are present at the back of the oral part of the tongue . They are arranged in a circular - shaped row just in front of the sulcus terminalis of the tongue .
