A+ Graded 100% Verified
Accommodation Reflex - ANS -The adjustment of the eyes for viewing at various
distances. Meaning the pupils will automatically constrict as objects move closer and
dilate as objects move further away.
Addiction - ANS -Habitual, psychological, and physiological dependence on a substance
beyond one's voluntary control.
Additive Effect - ANS -One mechanism of poly drug interaction. For a particular indicator
of impairment, two drugs produce an additive effect if they both affect the indicator in the
same way. (Cocaine-elevates PR + PCP-elevates PR= produces additive effect on the PR)
Afferent Nerves/Sensory Nerves - ANS -"Sensory Nerves" Nerves that carry messages to
the brain, from various parts of the body, including sense organs. (Afferent- "A **** thats
hot")
Alkaloid - ANS -Chemical that is found in, and can be physically extracted from, some
substance. EX: morphine is a natural alkaloid of Opium. It does not require a chemical
reaction to produce morphine form opium.
Analog (of a drug) - ANS -Analog of a drug is a chemical that is very similar to the drug,
both in terms of molecular structure and in terms of psychoactive effects. EX: Ketamine
is an analog of PCP.
Analgesic - ANS -A drug that relieves or allays pain.
Anesthetic - ANS -A drug that produces a general or local insensibility to pain and other
sensation.
Arrhythmia - ANS -An abnormal heart rhythm.
Artery - ANS -The strong, elastic blood vessels that carry blood away from the heart.
,Autonomic Nerve - ANS -A motor nerve that carries messages to the muscles and
organs that we do not consciously control. There are two types of autonomic nerves:
sympathetic & parasympathetic.
Axon - ANS -The part of a neuron (nerve cell) that sends out a neurotransmitter.
BAC - ANS -(Blood Alcohol Concentration)- the percentage of alcohol in a person's
blood.
BrAC - ANS -(Breath Alcohol Concentration)- the percentage of alcohol in a person's
blood as measured by a breath testing device.
Blood Pressure - ANS -The force exerted by blood on the walls of the arteries. Blood
pressure changes continuously, as the heart cycles between contraction and expansion.
Bradycardia - ANS -Abnormally slow heart rate.
Bradypnea - ANS -Abnormally slow rate of breathing.
Bruxism - ANS -Grinding the teeth. (Behavior often seen in a person who is under the
influence of cocaine/other CNS stimulant)
Cannabis - ANS -Drug category that includes marijuana, hashish, and marinol. Active
ingredient in marijuana and hashish is a chemical called delta-9 tetrahydocannabinol
(THC).
Carboxy THC - ANS -A metabolite of THC (tetrahydrocannabinol).
Cheyne-Stokes Respiration - ANS -Abnormal pattern of breathing. Marked by
breathlessness and deep, fast breathing.
CNS (Central Nervous System) - ANS -A system within the body consisting of the brain,
the brain stem, and spinal cord.
CNS Depressants - ANS -One of the seven drug categories that include: combinations,
anti-depressants, barbiturates, anti-anxiety tranquilizers, non-barbiturates,
anti-psychotic.
What does CABANA stand for and what drug category is it associated with? - ANS
-C-combinations, A-anti-depressants, B-barbiturates, A-anti-anxiety tranquilizers,
N-non-barbiturates, A-anti-psychotic. It is associated with the CNS Depressants category.
CNS Stimulants - ANS -One of the seven drug categories. CNS stimulants include:
Cocaine, amphetamines, and others.
, Conjuctivitus - ANS -An inflammation of the mucous membrane that lines the inner
surface of the eyelids caused by infection, allergy, or outside factors. Commonly known
as "pink eye".
Convergence - ANS -The "crossing" of the eyes that occurs when a person is able to
focus on a stimulus as it is pushed slowly toward the bridge of their nose. (See also
"Lack of convergence")
Crack/ Rock - ANS -Cocaine base, appears as a hard chunk from resembling pebbles or
small rocks. It produces a very, intense but relatively short duration "high."
Cirriculum Vitae - ANS -A written summary of a person's education, training, experience,
noteworthy achievements and other relevant information about a particular topic.
Cyclic Behavior - ANS -A manifestation of impairment due to certain drugs, in which the
suspect alternates between periods (or cycles) of intense agitation and relative calm. EX:
sometimes observed in subjects on PCP.
Delerium - ANS -A brief state characterized by incoherent excitement, confused speech,
restlessness, and possible hallucinations.
Dendrite - ANS -The part of a neuron (nerve cell) that receives a neurotransmitter.
Diacetyl Morphine - ANS -The chemical name for Heroin.
Diastolic - ANS -The lowest value of blood pressure. The blood pressure reaches its
diastolic value when the heart is fully expanded, or relaxed (diastole).
Diplopia - ANS -Double vision.
Dissociative Anesthetics - ANS -One of the seven drug categories that include drugs that
inhibits pain by cutting off or disassociating the brain's perception of pain.
Divided Attention - ANS -Concentrating on more than one thing at a time. The four
psychophysical test used by DREs require the subject to divide their attention.
What are the divided attention psychophysical test a DRE conducts? - ANS -Modified
Romberg, Walk & Turn, One Leg Stand, & Finger to Nose.
Downside Effect - ANS -An effect that may occur when the body reacts to the presence
of a drug by producing hormones or neurotransmitters to counteract the effects of the
drug consumed.
