    ans....
    2.a --both the lingual & inferior alveolar nerves are located superficially
    3.d --cementum is supposed to be an avascular tissue,if i remember
    4.d --because the other 3 options aren't possible


    ans for the 1st one,i'm not sure too...havent heard of "eleiden" what is it ? .epidermis also lacks blood supply.the blood capillaries are present only beneath the epidermis.it derives the nutrients only from dermis..

    -well this is what i think.....pls correct me if i'm wrong .
