History US Government. The Ninth Amendment was part of the Bill of Rights that was added to the Constitution on December 15, 1791. It says that all the rights not listed in the Constitution belong to the people, not the government. Judge Robert Bork called the Ninth Amendment a meaningless inkblot on the Constitution. 2  The Ninth Amendment was cited by the Supreme Court in the famous Roe v. Wade case. 3  Some judges have said that this amendment is not a source of additional rights, but simply a rule about how to read the Constitution.
Additional Readings. Systemic arterial blood pressure usually is measured using an instrument called a sphygmomanometer. This device consists of an inflatable rubber cuff connected by tubing to a compressible bulb and a glass tube containing a column of mercury.
Either a sphygmomanometer or a special machine is used to measure blood pressure. During this procedure, two numbers are recorded -- one appearing over the other as a fraction. The top number represents pressure when your heart is beating; the bottom number measures pressure when your heart is resting. The unit used when taking a blood pressure reading is millimeters of mercury (mmHg).
