I believe you mean mid-ocean ridge?
If so, true. 
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics.
This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary. 
A mid-ocean ridge demarcates the boundary between two tectonic plates, and consequently is termed a divergent plate boundary.
  
        
                    
             
        
        
        
Poor blood circulation will likely reduce the contraction power of a person's myosin.
<span>Myosins are motor proteins and they play a major role in muscle contraction and in a wide range of other motility processes in eukaryotes.
They depend on the ATP and are also responsible for actin-based motility.
</span>They are also used to produce <span>mechanical energy that is </span>used in various body<span> functions such as muscle movement and contraction.</span>
