  • Front
  • Back
process that occurs when a drug moves across membrane barriers into the bloodstream
an attractive force between chemicals and receptors that causes them to enter into and remain in combination (unique for each drug)
chemical substance that binds to certain receptors selectively and produces specific pharmacological effects
chemical substance that can bind to the same receptor as an agonist, but does not produce their effects
group of neural structures including nerves, nuclei, and ganglia which manage involuntary functions such as the regulation of blood pressure and body temperature
nerve fiber that conducts information AWAY from the nerve cell body to the axon terminal
group of structures in the brain just below the cortex that are important in the coordination of body movements
basal ganglia
structures in the lower part of the brain
brain stem
brain and spinal cord portions of the nervous system
small globe-like structure that overlies the medulla and pons and that maintains equilibrium, coordination, and mobility
largest part of the human brain, this structure is responsible for all higher-level function such as thinking and creativity; the cerebrum
cerebral cortex
fibers that conduct infomration TOWARD the nerve cell body of a neuron
sedatives, hypnotics, and tranquilizers such as Seconal, Halcion, Valium, and ethanol - or beverage alcohol
experience of feeling sandess, "down", "blue", and self-deprecating. In its more severe forms, it may be a more chronic and debilitating condition
measurement of how much drug is present in a body fluid or tissue
drug testing
process by which a drug moves through the bloodstream and into the brian and other tissues
substances which have an effect on the structure or function of the body
maximum effectiveness of a drug; also, whether a given treatment works
substances made by the body and belonging to the opiod class of substances; also called opioid peptides
process by which a substance passes from the body, or from a bodily organ, usually into the blood stream; this can be through urine, sweat, exhalation, and feces
recurrence of a drug-like sensations after not using the specific drug for weeks or months
major disturbance of reailty testing that has no clearly identifiable organic cause
functional psychosis
amount of time it takes to eliminate half of the drug present in the body
category of substances that produce a distortion or objective reality; sometimes called psychedelics, phantastics, or psychotomimetics
area of the brain that plays a critical role in consolidating new memory
brain structure involved in the processing of sensory informaiton and controlling vital body functions such as breathing, circulation, and body temperature
volatile solvents and nitrites that are used by inhalaiton
group of subcortical regions of the brain that are linked together and are associated with emotion
limbic system
fab soluble ("lipid loving") drugs
lowerst part of the brain, just above the spinal cord; this region maintains the basic drive and rhythms of essential functions like breathing and blood pressure
chemical changes in living cells by which energy is provided for vital processes, substances are broken down, and new material is assimilated to maintain structure and function of the body
region of the brainstem that influences the excitability of higher centers
chemical substance that produces an effect at a low dose, but at a high dose limits its own effect
mixed agonist/antagonist
nerve cell, consisting of a soma (or cell body), dendrites, and an axon
chemical substances that transmit information across synapses to other neurons
drugs in the inhalant category; sometimes referred to as "poppers" and "snappers"
drugs that bind to opioid receptors without producing any effects
opioid antagonists
all of the natural and synthetic substances that act like the primary active drug we get from the opium poppy, morphine
major disturbances of reality testing due to a dysfunction of the brain
organic psychosis
component of the A.N.S.
drug that produces less than the full effect expected of an agonist
partial agonists
portion of the nervous system which is comprised of sensory and motor nerves
altered biological state of a person who uses an addictive substance excessively and repeatedly; abstinence results in a physical withdrawal syndrome
physiological dependence
area of the brain just forward of the medulla
drugs that produce more of an effect at a particular dose than other; relatively stronger
the strongly held belief that a regular schedule of alcohol or other drug use is a necessity for normal functioning
psychological dependence
major disturbances of reality testing that also typically involve major changes in sense of self and ability to consciously control and regulate one's own behavior
substance that alters mood, though processes, and perception of reailty, and possesses a "rewarding" influence
psychotropic drug
site on a cell membrane that has a complementary chemical structure to a neurotransmitter
categories of psychotropic drugs according to their potential for abuse; dependency, and the existence of an acceptable medical use in this country
one of the three main parts of the neuron; cell body
category of psychotropic drugs; stimulants can increase the user's alertness, sense of strength, and sense of well being, and decrease appetite
nerves that comprise one component of the A.N.S.; when stimulated, sympathetic nerves produce an elevation of blood pressure, increase in pulse rate, and a rise in body temperature
the space across which information is transmitted between neurons
a brain structure involved in the processing of sensory information
decreased effect of the same dosage of alcohol or other drug; adaptation to their effects, such that higher dosages are required to produce the same effect
sacs that store neurotransmitters that are located in the axon terminals
