5 True/False questions
The _______, carries sensation regarding smell from the olfactory epithelium in the roof of the nasal cavity → olfactory nerve (CN I)
The nerve supply to the anterior-superior portion of the nasal mucosa is
from the ______ by way of the → ophthalmic nerve (V1); anterior and posterior
ethmoidal nerves, branches of the nasociliary nerve
Sensation from external nose → facial and ophthalmic arteries
Arterial supply of nasal cavity → muscle that tenses the soft palate during swallowing. It runs from the medial pterygoid plate, sphenoid spine and auditory tube
to the soft palate. Its tendon loops around the pterygoid hamulus (of medial pterygoid plate). It is innervated by the Mandibular division of the
Trigeminal Nerve (V3).
Foramen rotundum allows the pterygopalatine fossa to communicate with the → middle cranial fossa
