A new study finds the key role of bone in regulating the fight or flight response. In response to alarm signals from the brain, nerves within bone release osteocalcin, which immediately lowers the parasympathetic "brake" and lets the fight or flight response take over!

This research is no surprise to anyone that studies or works with fascia, the connective tissue network of the body that is especially dense around the muscles. Fascia is known to play a huge role in the fight or flight nervous system and is also continuous with bone.
Although we think of bone as "solid," 20% of it is actually water, and electrical charges and movement of this water transmits mechanical messages through bone, just like it does through fascia. In fact some scientists call bone "mineralized fascia."
According to a recent review article, "bone is part of the fascial continuum...that constantly transmits and receives mechano-metabolic information." https://www.cureus.com/articles/16943-bone-tissue-is-an-integral-part-of-the-fascial-system
It is fascinating to see how scientists are unravelling the complex interplay between the nervous and musculoskeletal systems!
