    Head & Neck

    Advertisements



    Post tonsillectomy, a 9-year old girl has a loss of taste sensation on the posterior 2/3 of her tongue. The nerve that has been injured is the

    a. lingual
    b. chorda tympani
    c. glossopharyngeal
    d. hypoglossal
    I used to pray and pray for a bike and never got one. Later I learned that God doesn't work that way... so I went out and stole a bike and asked God for forgiveness.

    N.IX can be injured during tonsillectomy because it is near tonsilla palatina

    Correct!

    The glossopharygeal n., CN IX, relays general sensory and taste sensation to the posterior 1/3 of the tongue. The anterior 2/3 portion is innervated by the lingual (general sensory) and chorda tympani (taste).
