Structural anatomy of the human head

Successive frontal slices of adult male, brain removed.

As can be seen in these images, the human skull is a rather complex maze of hollow cavities, thin walls, and hidden structures.

There are four sets of paranasal sinuses in the front of the head: the maxillary sinuses (right below the eyes), frontal sinuses (above the eyes, in the hard part of the forehead), ethmoid sinuses (between/behind the nose and eyes), and the sphenoid sinuses (in the sphenoid bone, under the pituitary gland, in the center of the skull - can be seen in the bottom-most plates).

In addition to those sinuses, you can also see the Eustachian tubes, which connect the ear to the nasopharynx and regulate pressure in the middle ear; the curled nasal concha, which regulate the air flow through our nose, keeping it a relatively constant humidity and temperature; and the falx cerebri, a sickle-shaped sheet of dura mater that divides the right and left hemispheres of the brain.

Ran Hwang is best known for her wall sculptures that make use of common objects like buttons and crystals pinned directly onto the wall of the gallery. Using each element like a pixel on a scren, Hwang creates oversized murals.
