Inside everybody’s nose
There lives a sharp-toothed snail.
So if you stick your finger in,
He may bite off your nail.
Stick it farther up inside,
And he may bite your ring off.
Stick it all the way, and he
May bite the whole darn thing off.
by Shel Silverstein from Where the Sidewalk Ends
If you stuck your finger far enough up your nose, could you reach your brain?
No, because an average-shaped human finger would not be able to pass beyond the nasal passages. If a finger (and it would have to be unfeasible small to do so) could make its way through the nasal passages, it would then reach the sinuses. Sunuses are air-filled spaces found behind the nose and cheeks and in the forhead. However, our imaginary finger would then find its route blocked by the cribriform plate, which makes up part of the ethmoid bone in the skull and forms the “ceiling” of your nose.
