Inhalants

Question 1: Inhalants, like hair spray, gasoline and spray paint can often be identified by their:

1. Strong smell

2. Myelin

3. Extra oxygen

4. Their usefulness

 

Answer

1. Strong smell
Yes! Many inhalants can be identified by their strong smell. People inhale the vapors because vapors can change the way the brain works and make people feel good for a short time.

2. Myelin

No, Myelin is a fatty tissue that protects many of the body's nerve cells. While myelin is affected by inhalants, myelin itself is not a characteristic of inhalants.

3. Extra oxygen

No, Inhalants harm the brain by preventing neurons from receiving oxygen. Then the neurons may stop functioning, making it hard to remember things such as schoolwork.

4. Their usefulness

No, while many inhalants are household products or art supplies, you can't really identify inhalants by their usefulness.

 

Question 2: Inhalant vapors may get lodged in a fatty tissue of neurons called:

1. Myelin

2. Noradrenaline

3. Frontal Cortex

4. Polyneuropathy

 

Answer

1. Myelin
Yes! Myelin is the protective cover that surrounds many of the body's nerve cells. When chemicals from inhalants get into the system, they can break down myelin and prevent nerve cells from transmitting messages.

2. Noradrenaline

No, Noradrenaline is a neurotransmitter that causes the heart to beat faster. Inhalants can make the heart more sensitive to noradrenaline so that even a normal jolt of it may cause a heart to lose its rhythm or even stop.

3. Frontal Cortex

No, This is the part of the brain that solves complex problems and plans ahead. When inhalants are ingested, nerve cell activity in the frontal cortex can be slowed. But the frontal cortex isn't a fatty tissue.

4. Polyneuropathy

No, Polyneuropathy is a permanent change or malfunction of nerves in the back and legs that can be caused by inhalant use.

 

Inhalants

Question 3: Butane, found in cigarette lighters and refills, makes the heart extra-sensitive to:

1. Myelin

2. Noradrenaline

3. The hippocampus

4. Romance

 

Answer

1. Myelin

No. Myelin is the fatty tissue that protects many of the body's nerve cells. Inhalants may deplete myelin content, but they don't make the heart more sensitive to myelin.

2. Noradrenaline
Correct! The chemical noradrenaline tells the heart to beat faster when you are stressed. Butane makes the heart extra-sensitive to noradrenaline so that a normal jolt of noradrenaline can cause the heart to lose rhythm or stop pumping.

3. The hippocampus

No. The hippocampus, the part of the brain which is important in memory, doesn't really have an effect on the heart. Sniffing inhalants, though, does damage it. Someone who repeatedly inhales these drugs may lose the ability to learn new stuff.

4. Romance

No. Inhalants can actually interfere with romance by causing a person to be slow, clumsy, and uncoordinated.

 

Inhalants

Question 4: Damage from long-term use of inhalants can slow or stop nerve cell activity in some parts of the brain including:

1. Frontal cortex

2. The liver

3. The heart

4. Gluteous maximus

 

Answer

1. Frontal cortex
Yup! This is the part of the brain that solves complex problems and plans ahead. If the frontal cortex is damaged, you could find yourself continuously stumped in school.

2. The liver

The liver is not part of the brain. But use of inhalants can cause the liver to stop working, which can lead to death.

3. The heart

While inhalants can slow, stop or make the heart lose rhythm, the heart isn't part of the brain.

4. Gluteous maximus

Hardly! The gluteous maximus is Latin for your royal backside. Scientists haven't yet documented any of inhalants' effects on the rump.

 

Hallucinogens

Question 1: The word hallucinate comes from the latin words meaning:

1. To wander in the mind

2. To slip

3. To slow

4. To disrupt

 

Answer

1. To wander in the mind
Yup! No wonder some people refer to hallucinating as tripping. Hallucinogens powerfully affect the way our five senses work, and change our impressions of time and reality.

2. To slip

The influence of hallucinogens does make your brain lose control of how you perceive the world. In fact, senses seem to get crossed - giving the feeling of hearing colors and seeing sounds. However, this wasn't the answer we were looking for.

3. To slow

In some people hallucinogens can cause drowsiness, but this is not the correct answer.

4. To disrupt

Hallucinogens can disrupt how the brain works, but this isn't the answer we were looking for.

 

Hallucinogens

Question 2: MDMA and MDA cause neurons to release the neurotransmitter serotonin. This can cause which of the following:

1. Ulcers

2. Change in behavior

3. Gingivitis

4. Gray hair

 

Answer

1. Ulcers

Ulcers are medical conditions in which there are sores on a sensitive lining such as the stomach. Ulcers aren't caused by the release of serotonin.

2. Change in behavior

Correct! Serotonin neurons have a role in lots of things such as mood, and sleep. MDMA and MDA can disrupt the function of these neurons and alter behavior.

3. Gingivitis

Although gingivitis is a disease, it is caused by poor dental hygiene. While serotonin doesn't play a role in getting gingivitis, we just wanted to remind you to keep up the good brushing.

4. Gray hair

Gray hair is not caused by the neurotransmitter serotonin, but your parents may get gray hair if you abuse MDMA, MDA or any illicit drug.

 

Hallucinogens

Question 3: LSD and PCP can change the way that neurons communicate, which can cause changes in the way you sense the world around you. Which of the following is used by neurons to communicate:

1. Chemical Changes

2. Chromosomes

3. Morse Code

4. Internet

 

Answer

1. Chemical Changes

Right! Chemical messengers, or neurotransmitters, send information from nerve cell to nerve cell in the brain and body. These speedy couriers trudge through wind, hail, sleet and snow to deliver your nervous system messages on time!

2. Chromosomes

Chromosomes carry the genetic code (genes) for the production of neurotransmitters, but they themselves are not used by neurons to communicate.

3. Morse Code

Morse code is a system of communication that consists of either long and short sounds or dots and dashes to transmit messages. Although morse code can be used to transmit messages over long distances, it is not used by neurons to communicate.

4. Internet

Nope, although the computer system you're accessing these questions off of is kind of like a brain. The computer network around the world does constantly send messages back and forth with amazing speed, much like your brain and body.

 

Hallucinogens

Question 4: Some hallucinogens are natural. However, many hallucinogens are chemicals that don't occur in nature. Can you identify some of these?

1. LSD and PCP

2. Mescaline

3. Gasoline

4. Serotonin

 

Answer

1. LSD and PCP

Correct! Lysergic acid (LSD) and phencyclidine (PCP) are powerful hallucinogens which aren't found in nature. The effects of these drugs are unpredictable: they can alter your senses, affect your moods, or cause vivid hallucinations.

2. Mescaline

While mescaline is a potent hallucinogen, it is found in nature. Mescaline comes from a cactus called peyote.

3. Gasoline

Gasoline is an inhalant, not a hallucinogen. But it is a chemical you should be wary of.

4. Serotonin

Serotonin is a neurotransmitter, not a hallucinogen. But hallucinogens can affect neurons that contain serotonin.

 

Marijuana

Question 1: Tetrahydrocannabinol is:

1. A high tech gasoline

2. A chemical in marijuana

3. A brain neurotransmitter

4. A dinosaur in Jurassic Park

 

Answer

1. A high tech gasoline

No. Despite its technical sounding name, this chemical has no ties to the gasoline we use in cars. Try again!

2. A chemical in marijuana

Yes! Tetrahydrocannabinol, or THC for short, is the main psychoactive ingredient in marijuana.

3. A brain neurotransmitter

No. Although it can act at the same receptors as the brain's neurotransmitter anadamide, tetrahydrocannabinl itself is not a neurotransmitter.

4. A dinosaur in Jurassic Park

No. Don't confuse this chemical with the dinosaur Tyrannosaurus Rex.

 

Marijuana

Question 2: The hippocampus is:

1. A brain area for memory

2. A summer camp for hippos

3. A brain area for hearing

4. A part of the liver

 

Answer

1. Yes!

The hippocampus is one of the places in the brain that helps us remember important things such as the information we need to pass an upcoming biology quiz. Because the hippocampus has lots of receptors for tetrahydrocannibinol, the active ingredient in marijuana, marijuana is able to act in the hippocampus to reduce memory.

 2. A summer camp for hippos

No. Though it might sound like a cool hangout place for hippos, remember the hippocampus is one of our brain areas that actually help us to remember.

3. A brain area for hearing

No. There are many brain areas that have a role in hearing, some of which are affected by marijuana, but the hippocampus is not one of them.

4. A part of the liver

No. The liver plays an important role in the breakdown of all drugs that enter the body, but it does not have a hippocampus.

Answer

1. The cerebral cortex

No. But through its actions in the cerebral cortex, marijuana can change a user's sense of smell, vision, hearing, taste, and touch.

Try again!

2. The limbic system

No. But marijuana does act in the limbic system to produce feelings of euphoria.

3. The hippocampus

No. But users of marijuana may have trouble remembering things because of marijuana's effects on the hippocampus.

4. The cerebellum

Yes! The cerebellum is one of the most important brain areas for balance and coordination. It also contains lots of receptors for tetrahydrocannabinol, the active ingredient in marijuana, which is why someone who uses marijuana may have difficulty keeping his or her balance.

2. Amygdala

No. The amygdala isn't a chemical. It's an important brain region that helps you feel pleasure.

3. Chocolate

No. Although chocolate can make your brain feel good, there are no chocolate chemicals in the brain.

4. Dopamine

Yes! Dopamine, which is sometimes called the pleasure chemical, has a shape and chemical structure that is similar to Methamphetamine. This is part of why Methamphetamine is able to cause its many effects in the brain.

 

Methamphetamine

Steroids

Question 1: The word "anabolic" means...

1. Growing or building

2. Swelling

3. Estrogen

4. Googol

 

Answer

1. Growing or building

Correct! Athletes abuse anabolic Steroids in order to artificially increase muscle mass. Some people like to look big even if it means doing ugly things to their insides.

2. Swelling

Well, the types of Steroids that are prescribed by doctors to reduce swelling are called corticoSteroids and are not addictive. When medication is taken in moderation it can be very helpful to a patient.

3. Estrogen

Wrong! Estrogen is any of several major female hormones that develop and maintain secondary female characteristics such as breasts. Both girls and boys have a balance of female male hormones.

4. Googol

No, but interesting anyway! Coined by the U.S. mathematician Edward Kasner's nephew, this term represents a number that is equal to one followed by 100 zeros and is expressed as 10 100.

 

Steroids

Question 2: The body's defense against germs and diseases is called...

1. The metric system

2. The hypothalamus

3. The immune system

4. The limbic system

 

Answer

1. Heartburn

2. Fibrillation

3. A slower heart rate

4. More oxygen to get to the heart

 

Answer

1. Heartburn

Uh Uh! Heartburn has nothing to do with the heart. It's actually a problem with the stomach that is caused by excess acid.

2. Fibrillation

Correct! Cocaine can cause blood vessels to narrow, which causes the heart to beat faster. Fibrillation is when it beats so fast that it loses its natural rhythm.

3. A slower heart rate

No! Cocaine actually causes the heart to beat faster.

4. More oxygen to get to the heart

No. Cocaine reduces the amount of oxygen that gets to the heart by reducing blood flow to the heart. Remember, blood carries oxygen.
