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
Cilia VS. microvilli. Both cilia and microvilli contain protein fibers which extend outward to provide shape for the structure. Cilia are larger in length and diameter than microvilli. Cilia are made up of microtubules which contain (9+2) ultrastructure. Microvilli are made of microfilament which lacks (9+2) ultrastructure. Cilia are not surrounded by glycocalyx layer. Microvilli are surrounded by glycocalyx layer. Cilia are taper distally. Microvilli are extremely thin and short.
