All Flashcards
What are the effects of multiple sclerosis?
Damage to myelin impairs signal transmission, leading to motor and sensory problems.
What are the effects of Myasthenia Gravis?
Antibodies attack acetylcholine receptors, weakening muscles.
What are the effects of alcohol on the brain?
Impaired judgment, coordination, and memory due to decreased neural activity.
What are the effects of stimulants on the nervous system?
Increased neural activity and arousal, leading to alertness and energy.
What are the effects of depressants on the nervous system?
Decreased neural activity, leading to sedation and relaxation.
What are the effects of hallucinogens on perception?
Perceptual and cognitive distortions, including vivid hallucinations.
What are the effects of drug tolerance?
The brain adapts, requiring higher doses to achieve the same effect.
What are the effects of drug addiction?
Compulsive use despite negative consequences, due to the brain's reward system being hijacked.
What are the effects of drug withdrawal?
Symptoms occur when stopping drug use as the brain readjusts to the absence of the drug.
How are SSRIs used in mental health?
As antidepressants, they block serotonin reuptake, improving mood.
How does caffeine affect alertness?
It blocks adenosine, increasing neural activity and alertness.
How do opioids affect pain?
They mimic endorphins, providing powerful pain relief and inducing euphoria.
Compare agonists and antagonists.
Agonists mimic or enhance neurotransmitter effects, while antagonists block them.
Compare stimulants and depressants.
Stimulants increase neural activity, while depressants decrease it.
