Traffic School, Drivers Ed Answers ★ Use of Alcohol, Drug Affect the Brain 3

When dopamine levels are elevated this reward pathway reinforces the use of the drug.
A.) TRUE
B.) FALSE

Get the Correct ANSWER

TRUE

All drugs of abuse activate the dopamine system in the reward pathway. Addictive drugs activate the reward system via increasing dopamine neurotransmission. Each drug has a different mechanism of action, each drug increases the activity of the reward pathway by increasing dopamine transmission. This reward pathway reinforces the use of the drug when dopamine levels are elevated.

---

When dopamine levels are_______this reward pathway reinforces the use of the drug.
A.) decreased
B.) the same
C.) elevated

Get the Correct ANSWER

elevated

There are_______major neurotransmitters that appear to account for most of the effects produced by the action of drugs of abuse on the brain.
➜ How many major neurotransmitters that appear to account for most of the effects produced by the action of drugs of abuse on the brain.
A.) five
B.) six
C.) seven
D.) eight

Get the Correct ANSWER

eight

There are seven major neurotransmitters that appear to account for the effects produced by the actions of drugs and alcohol abuse.These neurotransmitters include Dopamine, Serotonin, Norepinephrine, Endogenous opioids (endorphin and enkephalin), Acetylcholine, Endogenous cannabinoids (anandamide), Glutamate and Gamma-aminobutyric acid (GABA)

True or False: Alcohol and other drugs affect the nerve cells within the brain.
A.) TRUE
B.) FALSE

Get the Correct ANSWER

TRUE

HINT: Alcohol and other drugs acts primarily on the nerve cells within the brain. Alcohol interferes with communication between nerve cells and all other cells, suppressing the activities of excitatory nerve pathways and increasing the activities of inhibitory nerve pathways.

True or False: Alcohol is a solvent and dissolves brain cells and supporting tissues.
A.) TRUE
B.) FALSE

Get the Correct ANSWER

TRUE

C.) electrons
D.) protons

Get the Correct ANSWER

neurons

True or False: The brain plays no role in addiction.
A.) TRUE
B.) FALSE

Get the Correct ANSWER

FALSE

HINT: Various emotional brain systems that may play a role in drug addiction. Our main inhibitory neurotransmitter. It works as a natural tranquilizer, stops us from being impulsive and prevents over stimulation and also plays a major role in alcohol addiction. With repeated use of a drug, the neurons, which are where the neurotransmitters like dopamine reside, in the brain become dependent upon the drug. Most addictions are a result of chemical state alterations in the brain.

The Medulla controls your involuntary actions
A.) TRUE
B.) FALSE

Get the Correct ANSWER

TRUE

EXPLANATION: Medulla oblongata is the most vital part of the brain that controls and coordinates all involuntary actions (Autonomic Functions). Involuntary actions are actions which cannot be controlled by our conscious mind/control. For instance, heartbeat, digestion, blood vessel function, swallowing, breathing, blood pressure, peristalsis, sneezing and the rate of respiratory movements.

➜ The Frontal Lobe of the brain is for driving a motor vehicle.
A.) Essential
B.) Not used
C.) Not neccessary

Get the Correct ANSWER

Essential

The frontal lobe is essential for driving a motor vehicle as the frontal lobe controls judgment, emotions, decision making and awareness.

Your brain is involved in regulating different aspects of personality and bodily functions.
A.) TRUE
B.) FALSE

Get the Correct ANSWER

TRUE

EXPLANATION: Research shows that alcohol affects the brain and the central nervous system more than it does any other area of the body. This organ is perhaps the most important one because it regulates several complex bodily functions such as circulation, breathing and digestion. The brain also controls the processing of information as well as your emotions and memory, which you need for complex tasks like driving. Any alcohol you drink is quickly absorbed into the bloodstream and then heads to the brain. The alcohol that reaches the brain can cut off oxygen and kill brain cells. It slows down and impairs your reasoning and motor skills, which increases your reaction time.
