    from the ______ by way of the
    ophthalmic nerve (V1); anterior and posterior
    ethmoidal nerves, branches of the nasociliary nerve


  3. Sensation from external nosefacial and ophthalmic arteries


  4. Arterial supply of nasal cavitymuscle that tenses the soft palate during swallowing. It runs from the medial pterygoid plate, sphenoid spine and auditory tube

    Trigeminal Nerve (V3).
