Trigeminal nerve
The trigeminal nerve is the largest cranial nerve. It is the great sensory nerve of the head and face and the motor nerve of the muscles used for chewing. It emerges from the side of the pons, near its upper border, by a small motor and a large sensory root—the former being situated in front of and medial to the latter.
Turbinate
The turbinates are bony projections which protude into each breathing passage. They increase the surface area of the inside of the nose and boost its "air conditioning'" and air-filtering functions. There are three turbinates (inferior, middle and superior) on each side of the sinuses.
