Polarization by Use of a Polaroid Filter. The most common method of polarization involves the use of a Polaroid filter. Polaroid filters are made of a special material that is capable of blocking one of the two planes of vibration of an electromagnetic wave.
ventricle of larynx the space between the true and false vocal cords. lateral ventricle the cavity in each cerebral hemisphere, derived from the cavity of the embryonic tube, containing cerebrospinal fluid. left ventricle the lower chamber of the left side of the heart, which pumps oxygenated blood out through the aorta to all the tissues of the body. Morgagni's ventricle ventricle of larynx. pineal ventricle an extension of the third ventricle into the stalk of the pineal body.
The ventricular system is continuous with the central canal of the spinal cord. The ventricles are filled with cerebrospinal fluid (CSF), which bathes and cushions the brain and spinal cord within their bony confines. CSF flows from the lateral ventricles via the foramina of Monro into the third ventricle.
