A seam on the outside of a steel water tank is often an indication of the presence of a diaphragm. Both bladders and diaphragms serve the same function, creating a pressure differential using compressed air that pushes against the water, ejecting it from the tank.
Exostosis is the medical term for an abnormal growth of bone within the ear canal. It is more commonly referred to as swimmerâs or surferâs ear.xostosis symptoms of include a decrease in hearing sensitivity possibly combined with an increased prevalence of ear infections. Early symptoms include water trapping in the ear canal after swimming. Sometime thereafter, debris trapping and infections make surgery necessary.
Exocytosis Definition. Exocytosis is a process by which a cell transports secretory products through the cytoplasm to the plasma membrane. Secretory products are packaged into transport vesicles (membrane-bound spheres).xocytosis is the process by which cargo-laden transport vesicles move through the cytoplasm to the plasma membrane. Once at the plasma membrane two different things can happen. Sometimes the vesicle can dock and wait for a secretion signal. This happens in calcium-dependent (regulated) exocytosis.
