Finally done!

Based off a chart that I created for my own reference a while ago; I’ve shared this with a number of folks who found it helpful, so I decided to turn it into a kind of infographic.

The more I read about the thyroid, the more amazed I am at how critically it is tied to our overall quality of life, and almost every aspect of our health. I’ve experienced this personally - aside from the standard low energy/cold hands/hairloss elements of hypothyroid, I also found that switching to a natural thyroid medication with both T3 and T4 substantially improved my PCOS symptoms - it brought my Testosterone down by almost 25%, back into a normal range. It also completely corrected muscle pain in my quads, which I had before thought was a bit of tendonitis that wouldn’t heal.

Man I could go on about thyroid for forever but I’d better stop….:)

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.
