Mechanosensation and Mechanotransduction
"the biological process of detecting and transducing mechanical forces- such as touch, sound, gravity, and pressure- into electrical or chemical cellular signals"
The process of converting mechanical forces into electrical signals (mechanotransduction) is possible by mechanoreceptor neurons
mechanoreceptor neuron on bone tissue is called "an osteocyte"
When an osteocyte is met with force, the movement of interstitial fluid in the narrow spaces around its cell body and dendritic processes in the lacuno-canalicular network cause the mechanosensitive ion channels to open, leading to rapid influx of ions (mainly Ca2)"the biological process of detecting and transducing mechanical forces- such as touch, sound, gravity, and pressure- into electrical or chemical cellular signals"

The second scenario is that force causes intracellular electrical/ionic changes
The Ca2 influx or electrical change activates intracellular pathways (e.g., ERK/MAPK, Akt, Wnt/β-catenin signaling)
Ca2 influx- the entry of extracellular calcium ions into the cytoplasm through plasma membrane channels
Plasma membrane channels- specialized transmembrane proteins that form hydrophilic pores, allowing passive transport of ions, water, and small polar molecules across the lipid bilayer

This alters gene expression, notably downregulating sclerostin (SOST) - a key inhibitor of bone formation
To the neighboring osteocyte what this does is- Signals propagate via gap junctions (primarily connexin-43, or Cx43) on the dendritic processes
These allow direct passage of small molecules like Ca2, IP3, or ATP between connected osteocytes
connexin-43/Cx43- responsible for intracellular communication
This creates a coordinated network response across the bone matrix
To the effector cells on the bones surface, signals reach osteoblasts and osteoclastsThis creates a coordinated network response across the bone matrix
This, (very oversimplified because the process is very detailed and i had trouble finding good research) inhibits osteoclast activity and upregulates osteoblast activity
ERK/MAPK, Akt, Wnt/β-catenin signaling-key intracellular signaling cascades that osteocytes activate (or modulate) after sensing mechanical stimuli like fluid flow shear stress or cytoplasm/interstitial fluid movement
This is the end of my thread, i wish at least one person looks into what i said and considers bonesmashing.
I truly wish to help you.
IF you have any question ask me here or im dm's, i will gladly answer anything
