McBurney's point is located midway between the anterior iliac crest and the umbilicus in the right lower quadrant. From Ignatavicius and Workman, 2002.
melting point (mp) the minimum temperature at which a solid begins to liquefy; see also freezing point.
near point the nearest point of clear vision, the absolute near point being that for either eye alone with accommodation relaxed, and the relative near point being that for the two eyes together with employment of accommodation.

triple point the temperature and pressure at which the solid, liquid, and gas phases of a substance are in equilibrium.

dew point

the temperature at and below which moisture will condense for a specific humidity.

dew point
