altar of incense, the ethmoid bone

Coming across an image of the ethmoid bone, I love its wild structure. I wonder where in the body is this angular (cubical) bone located?

Quickly I learn it is one of 8 bones of the cranium.

Look to the top centered, dark area inside and underneath ↑ the skullcap. This is one side of the ethmoid bone. It separates the nasal cavity from the brain.  (Man…do I really need to clean this skull. Though for this purpose the dirty area works as a marker.)

From the front of the skull, the Ethmoid bone sits at the roof of the nose, between the two orbits forming the inner edges of the eye sockets. Ethmos is Greek and means sieve. The bone is lightweight and spongy, full of air spaces and canals.

Neurons of smell travel thorough the ethmoid and the olfactory bulbs that lie atop, across what is called the cribriform plate. If this narrow and deeply grooved plate is broken one loses their sense of smell. All olfactory nerves travel through the crosses and canals of the ethmoid.

I enjoy drawing the front and back of this beautiful bone.

About its symbolism:
In more esoteric teaching it is called the altar of incense, representing the altar in the sanctuary.  The altar of incense is the place of prayer and this bone represent the principle of prayer.

Inhale deeply!  Consider the lovely ethmoid and know it connects to your sense of smell.
