Study These Flashcards
A

Slow-Wave Sleep Functions

24
Clenching or grinding teeth during sleep and headache or sore jaw. Need bite plate
Bruxism
25
Cessation of breathing during sleep, carbon dioxide increases in blood stream that triggers medulla and wakes you up to regulate CO2. Chronic fatigue, sleepy, obstruction in airways. Usually appears in males, unhealthy weight, and older. Can be fixed with healthy lifestyle, specialty pillow/beds, apparatus, of surgery to open airflow
Sleep Apnea
26
Sleep attack (irresistible urge to sleep for 5-10 minutes) Cataplexy (lose muscle tone when gets surprised and collapses) Sleep paralysis (become paralyzed as you are falling asleep or waking up) [hypnogogic-going to sleep/hypnopomic-waking up]
Narcolepsy
27
Lack of paralysis in REM sleep (act out dreams)
REM Without Atonia
28
Less than 4 hours of sleep and causes tiredness. Medication as a last resort, try relaxing before sleep (avoid bright lights, smoking, caffeine, alcohol, TV, etc). Try sleep schedule and use bed only for sleeping.
Insomnia
29
Two waves drugs are used
Recreationally and for Treatment
30
The world around can influence people's experienced in drug
Context (setting)
31
Can be uplifting, depressing, or aggressive depending on...
Personality or Mood
32
Decreased responsiveness to drug with repeated use
Tolerance
33
Upon discontinuation, user experience symptoms that are opposite to that of the drug
Withdrawal
34
Requiring the drug for normal physical and/or psychological functioning
Dependency
35
Decreases CNS activity, acts on GABA receptors, and creates feeling of relaxation and drowsiness
Depressants (Downers)
36
Acts on GABA, Endophrins, and Dopamine. Mild euphoria, anxiolytic, incoordination, and sedation. Can cause Korsakoff's Syndrome (cannot make new memories and mixed up current ones)
Alcohol
37
Relaxation, mild euphoria, decrease in muscle coordination, decrease in attention, induce deep sleep, disrupts sleep, and lethal when combined with alcohol
Barbiturates & Benzodiazepines
38
Naturally occurring substance similar to GABA. Relaxation, euphoria, increased sex drive, loss of inhibition, high risk of death by overdose, people mix them with floor cleaners and drain cleaners. Date rape drug.
GHB (Gamma Hydroxybutyrate)
39
Increased CNS activity
Stimulants (Uppers)
40
Reduces drowsiness, little evidence for cognitive performance, increase capacity of physical work, often used in medication for headaches, and can cause caffeineism (caffeine induced anxiety)
Caffeine
41
Acts on acetylcholine receptors, increases dopamine, arousal, alertness, attention, and improves memory
Nicotine
42
Acts on dopamine receptors in the brain, causes euphoric mood, increased self esteem, increased energy, less need for sleep, increased risk of Parkinson's Disease, induced psychosis that resembles schizophrenia (hallucinations, delusions, and violence), and self-mutilation (bugs under skin)
Cocaine & Amphetamine
43
Increase levels of serotonin in brain, causes euphoria, increased sex drive, visual hallucinations, heightened perception (taste, touch), depression & memory impairment observed in long term use
MDMA (Ecstasy)
44
Depress CNS activity and acts on endorphin receptors (reduce pain; analgesia)
Opiates (Narcotics)
45
Euphoria, can induce sleep, and decrease sex drive
Morphine & Heroine
46
Distortion a of reality and alters emotion and thoughts
Hallucinogens (Psychedelics)
47
Small amounts can have large effects, acts on serotonin receptors, visual hallucination, bright colours/synethesia, alter thoughts, block effects of alcohol, and no deaths from overdose
LSD
48
Other hallucinogens
Psilocybin, Ketamine, and Mescaline
49
Has properties of hallucinogens, depressants, and opiates, mild euphoria, intensifies sensation, time passes slowly, hallucinations, delusions, distortion of body image, can cause mild cognitive impairments, medical benefits, less harmful than other drugs, large effects on adolescent, and acts on cannabinoid receptors
Cannabis (Marijuana)
