your brain and alcohol instructions: in this activity, you will study how alcohol affects the brain. to begin, watch the online video “under construction: alcohol and the teenage brain” by turningpointtraining. then, using the information in lesson 12.1, label the parts of the brain affected by alcohol. then, describe how alcohol affects each area. finally, describe how alcohol’s effect on the area increases the chance of risky behaviors and injury. 1. what parts of the brain does alcohol affect? 2. how does alcohol affect each area? 3. how do alcohol’s effects increase the chance of risky behaviors and injury?

Question

Accepted Answer

# Brief Explanations:
Answers are based on biological knowledge of alcohol's effects on brain regions and subsequent behavioral impacts.

# Answer:
1. Alcohol affects parts of the brain including the cerebral cortex, cerebellum, hippocampus, amygdala, and brainstem.
2. Cerebral cortex: Impairs judgment and reasoning. Cerebellum: Disrupts coordination and balance. Hippocampus: Inhibits memory formation. Amygdala: Reduces inhibition, increasing impulsivity. Brainstem: Depresses basic functions like breathing and heart rate regulation.
3. Impaired judgment (cerebral cortex) leads to poor risk assessment; reduced inhibition (amygdala) increases impulsive actions; impaired coordination (cerebellum) raises accident risk; memory issues (hippocampus) may lead to repeated risky behaviors; brainstem depression can cause life-threatening injuries.
