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.

NUMBERS 25:4 PRAISE THE SUN!

you guys missed the best one 

¹¹ If two men are fighting and the wife of one of them comes to rescue her husband from his assailant, and she reaches out and seizes him by his private parts, ¹² you shall cut off her hand. Show her no pity. 

you know most of these come from the old testament right? you know that old testament that doesn’t apply since jesus came and really isn’t part of dogma anymore?

I’m guessing this is aimed at everyone, but yeah I personally know that º_o still funny to see how batshit insane OTG was.
