Answer: Subarachnoid
Explanation:
The  space in the meninges below the arachnoid membrane and above the pia mater  contains the cerebrospinal fluid. Cerebrospinal fluid is produced by choriod plexus( a cluster of capillaries) from the blood. Blood vessels traveling within the subarachnoid space deliver oxygen and nutrients  to the spinal cord.  
 
        
                    
             
        
        
        
Because humans eat both plants and meat
        
             
        
        
        
Bacteria and plants both have cell wall and this is the main similarity ! 
in accurate all bacteria, cell wall may not be present !
        
             
        
        
        
The clinical manifestations should the nurse expect are reports of leg fatigue, tortuous veins in the legs and pain in lower extremities when standing. 
In addition, leg fatigue is a communal clinical manifestation triggered by venous stasis and insufficient tissue oxygenation. The vein walls deteriorate and dilate causing distended, bulging veins that look tortuous and darkened. As vein walls weaken and dilate venous pressure increases and the valves turn out to be useless in which vein stasis and inadequate oxygenation end result is limb discomfort. The discolored toenails effect from a fungus below the nail or chronic hypoxia, not varicose veins, confined to a small area of heat in a calf is a mark of thrombophlebitis and reddened zones on a leg are symptomatic of thrombophlebitis.
