A

hormone secreted by the endocrine gland that serves as an important regulator of the sleep-wake cycle

24
Q

methadone

Study These Flashcards
A

synthetic opioid that is less euphorogenic than heroin and similar drugs; used to manage withdrawal symptoms in opiate users

25
methamphetamine
type of amphetamine that can be made from pseudoephedrine, an over-the-counter drug; widely manufactured and abused
26
morphine
narcotic; can treat moderate to severe pain

one of a category of drugs that has strong analgesic properties; opiates are produced from the resin of the opium poppy; includes heroin, morphine, methadone, and codeine
31
obstructive sleep apnea
sleep disorder defined by episodes when breathing stops during sleep as a result of blockage of the airway
32
parasomnia
one of a group of sleep disorders characterized by unwanted, disruptive motor activity and/or experiences during sleep
33
physical dependence
changes in normal bodily functions that cause a drug user to experience withdrawal symptoms upon cessation of use
34
pineal gland
endocrine structure located inside the brain that releases melatonin
35
psychological dependence
emotional, rather than a physical, need for a drug which may be used to relieve psychological distress
36
rapid eye movement (REM) sleep
period of sleep characterized by brain waves very similar to those during wakefulness and by darting movements of the eyes under closed eyelids
37
REM sleep behavior disorder (RBD)
sleep disorder in which the muscle paralysis associated with the REM sleep phase does not occur; sleepers have high levels of physical activity during REM sleep, especially during disturbing dreams
38
restless leg syndrome
sleep disorder in which the sufferer has uncomfortable sensations in the legs when trying to fall asleep that are relieved by moving the legs

46
stage 3 sleep
third stage of sleep; deep sleep characterized by low frequency, high amplitude delta waves
47
stage 4 sleep
fourth stage of sleep; deep sleep characterized by low frequency, high amplitude delta waves
48
stimulant
drug that tends to increase overall levels of neural activity; includes caffeine, nicotine, amphetamines, and cocaine
49
suprachiasmatic nucleus (SCN)
area of the hypothalamus in which the body’s biological clock is located
50
theta wave
type of low frequency, low amplitude brain wave characteristic of the end of stage 1 sleep
51
tolerance
state of requiring increasing quantities of the drug to gain the desired effect
52
wakefulness
characterized by high levels of sensory awareness, thought, and behavior
53
withdrawal
