The epithelium coating the urinary bladder surface is known as the urothelium. It is a specific kind of cell exhibiting high elasticity and numerous cellular activities. It signifies the initial line of bladder resistance and a boundary in between the defense mechanisms and pathogens. The purposes of the urothelium comprise immune responses, control of permeability, and communication between the cells that appears to perform the main role in reacting towards infections and injuries.  

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
