If the Blood-Brain Barrier Prevents Toxic Substances from Getting into the Central

question 58

Multiple Choice

If the blood-brain barrier prevents toxic substances from getting into the central nervous system, how does alcohol most likely impair a person's judgment?

• A) Alcohol acts on the peripheral nervous system, which then activates neurons in the cortex that impair judgment.
• B) Alcohol acts on the liver, creating toxins that can cross the blood-brain barrier, which then activate neurons in the cortex that impair judgment.
• C) Alcohol decreases blood oxygen levels, which leads to impaired judgment.
• D) Alcohol can bind to glucocorticoid transporters in the brain, which causes impaired judgment by binding to neurons in the cortex.
• E) Because it is hydrophobic, alcohol can pass directly across the blood-brain barrier and cause impaired judgment by binding directly to neurons in the cortex.
