Muscle contractions then push the stool toward the rectum, and, by the time the stool reaches the rectum, most of the water has been absorbed, making the stool solid. When the colon's muscle contractions are slow or sluggish, the stool moves through the colon too slowly, resulting in too much water being absorbed.
The microparticulate allograft is a mixture of mineralized cortical bone particles of a standard combination of sizes between 100 and than 250 microns. This provides an optimal scaffold for delivering osteoinductive growth factors. This preparation has an appropriate 3-dimensional (3-D) structure
They are precisely etched scales, also of 100 equal graduations, but their size is known and constant. The total size of the stage micrometer is 1 millimeter (mm), so each graduation is .01 mm. That's equal to 10 micrometers (Âµm).See the summary of metric distances at the end of this chapter.est for goodness of fit with a (2 test. In this case, you will need to compare your reference value for significant differences to 5.991 rather than 3.841. As the number of phenotypic classes increases, so does the number that is used to compare with your (2 value.
