| refractive index |
A ratio between the velocity of light in air and that of light through a particular substance. The index of air is 1.00 and all indices are referred to the index of air, ie, the index of water being 1.33 means that the speed of light in air is 1.33 times greater as the speed of light in water.

| reflex |
An involuntary response of the nervous system to a stimulus, such as the stretch reflex, which is elicited by tapping a tendon with a reflex hammer, resulting in a contraction. Increased, diminished, or absent reflexes can be indicative of neurologic damage, including MS, and are therefore tested as part of the standard neurologic exam.
