Limb

 

a flat metal ring divided by lines into equal parts of circumference (for example, degrees or minutes). It is the most important part of instruments used in measuring angles (in astronomy, geodesy, physics, and so on); it gives a reading of the magnitude of the angle. The scale units of a limb are read by means of a vernier or a micrometric microscope.

Tolerance can be described in two ways: (1) Chronic tolerance is observed as a decrease in the magnitude of an effect of alcohol with repeated exposures; and (2) acute tolerance is observed within the course of the elimination of a single exposure and is characterized by a reduced alcohol effect on the descending limb of the breath alcohol concentration curve (BAC) when compared to the ascending limb.
