File S1 - The Influence of Body Position on Cerebrospinal Fluid Pressure Gradient and Movement in Cats with Normal and Impaired Craniospinal Communication

Figure S1. Small fluid element in motion and acting forces. Figure S2. Balance of the body and pressure gradient forces in a fluid column at rest in a tube closed at the top and opened at the bottom. Figure S3. Short narrow tube opened at one end immersed in incompressible fluid. Figure S4. Narrow tube closed at one or both ends. a) narrow tube partly immersed in incompressible fluid; and b) totally out of the container with opening at the top; and c) closed at both ends. Figure S5. Hydrostatic pressure in tube with different shapes. A and B represent “spinal” part; C and D represent “cranial” part of CSF system model. (DOCX)
