Accommodation Reflex - CORRECT-ANSWER-The adjustment of the
eyes for viewing at various distance. Meaning the pupils will
automatically constrict as objects move closer and dilate as objects
move further away.
,Addiction - CORRECT-ANSWER-Habitual, psychological, and
physiological dependence on a substance beyond one's voluntary
control.
Addictive Effect - CORRECT-ANSWER-One mechanism of polydrug
interaction. For a particular indicator of impairment, two drugs produce
an addictive effect if they both affect the indicator in the same way. For
Example, cocaine elevates pulse rate and PCP also elevates pulse rate.
The combination of Cocaine and PCP produces an additive effect on
pulse rate.
Alkaloid - CORRECT-ANSWER-A chemical that is found in, and can be
physically extracted from, some substance. For example, Morphine is a
natural alkaloid of Opium. It does not require a chemical reaction to
produce Morphine from Opium.

Antagonictic Effect - CORRECT-ANSWER-One mechanism of polydrug

example, Heroin constricts pupils while cocaine dilates pupils. The
combination of Heroin and Cocaine produces antagonistic effect on
pupil size. Depending on how much each drug was taken, and on when
they were taken , the suspect's pupils could be constricted, or dilated,
or within the DRE Average range of pupil size.
Arrhytmia - CORRECT-ANSWER-An abnormal heart rhythm
, Artery - CORRECT-ANSWER-The strong, elastic blood vessels that carry
blood away from the heart.
Autonomic Nerve - CORRECT-ANSWER-A motor nerve that carries
messages to the muscles and organs that we do not consciously
control. There are 2 kinds of autonomic nerves, the sympathetic nerves
and parasympathetic nerves.
Axon - CORRECT-ANSWER-The part of a neuron (nerve cell) that sends
out a neurotransmitter.
Bad Trip - CORRECT-ANSWER-A hallucination where the user becomes
