the following tests and procedures may be used: • physical exam and history • biopsy: the removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer after penile cancer has been diagnosed, tests are done to find out if cancer cells have spread within...
to stimulate the opening of channels through the membranes of muscle cells, which would result in normal muscle function. the regulation of transport, though a crucial function of the cell membrane, is not its only role. cell membranes assist in the organization of individual cells to form tissues....
and tissues with help of fluorophores one or more fluophores are added to certain parts of the specimen tissue or cells. when exposed to so-called "exicitation light", the fluorophore absorbs energy from the excitation light and emits ligth in another visible wavelengt. this make it possible to distinguish...
