    Anatomic Sciences, Booklet 1-M, Question 1

    Which of the following nerves innervates the interior buccal mucosa of the floor of the oral cavity?
    A. Facial
    B. Trigeminal
    C. Lingual
    D. Mylohyoid
    E. Hypoglossal

    Answer: Trigeminal

    While I agree that trigeminal is a possible answer, I wonder why the answer couldn't also be Lingual. According to the Decks, Lingual is a branch off V3 and provides general sensory innervation to the floor of the mouth (Note: See Nerves Section of Anatomic Sciences, if you are using the decks).

    Help!

    sensory innervation to Buccal mucosa of the floor of the mouth is supplied by Mental n. (a br. of IAN). If it was lingual, it would be lingual n. as you had suggested.

    Can you help me out with this question?

    What structure causes the bucal vestibule to decrease in size when the jaw is opened wide?
    -Condyle, coronoid fossa,hamular process,styloid process?

    I think is that the meniscus would decrease in size when the jaw is opening. but I'm not sure and there's no an option for that answer... :rolleyes:

    Thanks in advance;)
