That is a great dermatome map Justin. Though I know sometimes people can have symptoms that don't exactly correlate with the dermatome maps.

Yeah, that is very true. This dermatome map is "most likely" in the general population; however, we have unique anatomy for sure.

Interesting fact: close to 15% of Asian Americans have their piriformis muscle bifurcated by the sciatic nerve. (I'll have to pull that study up some day from my pile of papers).
