Vision and Hearing
- Light travels through the eye: light strikes rods/cones, optic nerves carry impulses, and the brain flips and combines images from both eyes to create a single, right-side-up image.
- Sound travels through the ear: sound enters the ear canal, vibrates the eardrum, vibrations reach the middle ear, are processed by auditory nerves, and are interpreted by the brain.
- Three ways to protect eye health: wear protective goggles, use sunglasses, and get regular eye exams.
- Important ear care practices: keep ears clean, monitor noise exposure, and consult a doctor for issues.
- The brain processes images from both eyes to combine slightly different perspectives into a single 3D image and correct the initial upside-down projection.
- The cornea is the clear front tissue covering the eye.
- The pupil is the opening for light entry.
- The iris is the circular muscle controlling pupil size.
- The lens focuses light onto the retina.
- The retina contains the light-sensitive cells.
- The eardrum vibrates when sound waves strike it, transmitting vibrations to the middle ear.
- The cochlea is a fluid-filled tube that converts sound vibrations to nerve signals.
- The semicircular canals detect head movements for balance.
- "Sound vibrations", not "sand vibrations" strike the eardrum.
- The iris adjusts pupil size to control light entering the eye, like a camera aperture.
Sleep Health
- Adequate sleep supports the immune system, enables healing, and helps prevent diseases like diabetes.
- Circadian rhythm is the body's natural 24-hour internal clock that regulates sleep/wake cycles.
- Teenagers naturally fall asleep later at night and wake up later due to biological shifts in their circadian rhythm.
- The body heals damaged tissues mainly during sleep.
Sleep Disorders
- Insomnia is characterized by difficulty falling or staying asleep, often caused by stress or physical issues.
- Sleep apnea causes temporary pauses in breathing followed by sudden restarts during sleep.
- Narcolepsy involves extreme/uncontrollable sleepiness or sudden sleep attacks during daytime activities.
- Using eye drops is not a way to protect your eyes.
- Benefits of sleep include learning, memory storage, disease prevention, and a proper immune system.
- The light path: light hits rods/cones, optic nerves transmit signals, and the brain processes the information.
- The brain flips the reversed image and combines inputs from both eyes.
Alcohol Education
- A drug is a chemical that changes behavior/body function.
- Alcohol is classified as a depressant that slows brain/body reactions.
- Fermentation produces alcohol as yeast microorganisms feed on sugars in grains/fruits, converting them to alcohol.
- A zero-tolerance policy means immediate strict consequences for any alcohol/drug possession, even first-time offenses.
- Depressants slow brain and body reactions.
- Intoxication impairs coordination.
- Intoxication slows brain activity.
Alcohol's Effects
- Alcohol's effects on the nervous system: slows reflexes, dulls perception.
- Alcohol's effects on the cardiovascular system: raises heart rate/blood pressure, lowers core temperature.
- Alcohol's effects on the excretory system: increases urine production, leading to dehydration risk.
- Alcohol's effects on the digestive system: may induce vomiting.
- Blood Alcohol Concentration (BAC) is the % alcohol in blood.
- Factors influencing BAC: body size, consumption speed, gender, stomach food content.
- Life-threatening risks of intoxication: drunk-driving accidents, alcohol poisoning (overdose), and dangerous drug interactions.
- Alcohol causes dehydration by suppressing antidiuretic hormone (ADH), causing kidneys to produce excess urine.
Alcohol's Effects - Key Vocabulary
- Intoxication is a state where alcohol/substances impair mental and physical abilities, slowing reflexes, dulling judgment, and reducing coordination.
- A blackout is a period of alcohol-induced memory loss.
- A hangover is the aftereffects of excessive drinking (headache, nausea, fatigue).
- An overdose can result in a coma or death.
- A legal consequence of DWI (Driving While Intoxicated) for drivers over 21: arrest for driving with BAC ≥ 0.08%.
- Binge drinking: consuming excessive alcohol in one session (e.g., 4+ drinks for women, 5+ for men in 2 hours).
- Overdose: taking a dangerous amount of a drug, potentially fatal.
- A blackout does not mean someone was unconscious; the person may function but won't recall events later.
- The consumer's race doesn't affect BAC.
- You can overdose on alcohol; alcohol poisoning can be fatal.
- Drinking alcohol impacts cardiovascular and excretory systems and the nervous system.
- Alcohol is a depressant because it slows body functions (CNS, reflexes, breathing).
- Negative impacts of underage drinking: long-term brain damage, injury/death in motor accidents, school/sports suspension.
- Alcohol's depressant effect slows reaction time, impairs coordination/judgment, and dulls perception, leading to higher crash risk.
Long-Term Alcohol Risks
- Long-term effects of alcohol abuse: brain damage (e.g., memory loss), heart disease (e.g., high blood pressure), liver damage (e.g., cirrhosis), digestive system problems (e.g., ulcers), and fetal alcohol spectrum disorders (in pregnancy).
- Alcoholism: a disease where a person loses control over alcohol use, despite negative consequences.
- Stages of alcoholism: peers or social occasions, increased tolerance.
- Recovery steps: Acknowledging the problem, Detoxification, Rehabilitation.
- Stage 2 (Absolute Dependence) is dangerous because loss of control over drinking leads to compulsive use, risking health/job/relationships.
- Tolerance refers to reduced effects over time, leading to a need for more alcohol for the same impact.
- Dependence: the brain chemically requires alcohol to function normally.
- Reverse tolerance: occurs after liver damage, resulting in very small amounts causing intoxication due to impaired metabolism.
- Detoxification removes alcohol from the body.
- Withdrawal includes symptoms when stopping alcohol such as shaking and nausea.
- Rehabilitation is the process of learning to live alcohol-free.
- Withdrawal symptoms indicate the body is detoxifying, but can be dangerous without medical supervision.
- Rehabilitation is critical after detox, as it teaches coping skills to prevent relapse.
Avoiding Alcohol
- Refusal skills include techniques to confidently say no, such as "No thanks, I don't drink," or "I'm staying in control tonight."
- Key benefits of avoiding alcohol-related situations: maintaining an alcohol-free lifestyle and reducing risks such as accidents and peer pressure.
- Healthy drink alternatives to alcohol: water or juice/soda, which keep you hydrated and avoid alcohol-related consequences.
- Respond to pressure to drink with: "I'm good with my soda—I've got plans later!" or "Not my thing, but you do you."
- "Fitness" is not a stage of recovery. The stages are: acknowledging the problem, detoxification, and rehabilitation.
- Long-term effects of alcohol abuse: liver damage, heart disease, fetal alcohol syndrome, brain damage, and digestive problems.
- Ways to keep friends safe at a party with alcohol: avoid alcohol areas, have a designated driver, and provide peer support.
- Acknowledging the problem is critical in recovery, because without admitting addiction, a person won't seek help or commit to detox/rehab.
- Binge drinking is consuming excessive alcohol in one sitting.
- The cochlea is the fluid-filled tube in the inner ear for hearing.
- BAC is the percentage of alcohol in the blood.
- Refusal skills is the ability to confidently say "no" to alcohol.
- Terms related to skin health: epidermis (outer skin layer) or acne (clogged hair follicles).
- Detoxification: removing alcohol from the body.
- Withdrawal: symptoms when stopping alcohol/drugs.
- "Insomnia is caused only by stress" is false, as physical factors, habits, or mental health can also cause it.
- Sleep cycles correlate with alcoholism.
- Circadian rhythm: disruptions can lead to insomnia, fatigue, and can hinder recovery.
- Ways to prevent tooth decay and gum disease: maintain a healthy diet, brush teeth, floss, wear a mouthguard and have regular dental checkups.
- The primary functions of hair: protect the scalp from sun, insulates and blocks debris.
- The primary functions of nails: Shield fingertips/toes.
- Ear-care practices: keep ears clean (avoid cotton swabs deep inside), monitor noise exposure (use ear protection) and seek medical help for pain/hearing loss.
