Sinus Anatomy. INTRODUCTION. The paranasal sinuses (âthe sinusesâ) are air-filled cavities located within the bones of the face and around the nasal cavity and eyes. Each sinus is named for the bone in which it is located: Physiology.The pink membranes lining the sinuses make mucus that is cleared out of the sinus cavities and drains into the nasal passage. The right and left nasal passages are separated in the middle by a vertical plate of cartilage and bone called the nasal septum (figures 1 and 2).ach sinus is named for the bone in which it is located: Physiology. The pink membranes lining the sinuses make mucus that is cleared out of the sinus cavities and drains into the nasal passage.

If a manufacturer calls his frequency generator a Rife machine then it could be considered medical equipment and regulated by the FDA. This is why Rifeâs name should never be used to define frequency generating equipment. Off-the-shelf frequency generators are considered electronic test equipment.r. Rife's machine output about 50 watts to 300 watts of power. Of course these high powered instruments used a Ray tube. If an instrument is so small that you can almost hold it in the palm of your hand you can be sure that it will never work the way Dr. Rife's machines worked.
