Question

directions: with a partner/small group, read the following scenarios and identify the part of the brain is being used or where sensations are being routed:

1. a student is running a marathon and suddenly collapses. paramedics arrive and check for vital signs, including heart rate and breathing. which part of the brain is primarily responsible for regulating heart rate and breathing?
2. during a boring lecture, a student starts to doze off but is suddenly awakened by a loud noise in the hallway. which part of the brain was activated to arouse the student and filter the sensory information?
3. a gymnast performs a complex routine involving flips and balance on a beam. which part of the brain is controlling coordination, muscle movement, and balance during the routine?
4. while eating at a restaurant, a student can hear conversations, smell food, and see the surroundings, but the sense of smell does not pass through this brain structure. which brain structure routes sensory information except for the sense of smell?
5. a student feels hungry and decides to eat a snack. later, they feel satisfied and stop eating. which part of the brain regulates hunger and other biological motivations?
6. a student recalls the information they studied for an upcoming test. which part of the brain is primarily involved in forming and retrieving memories?
7. a student is startled by a spider and reacts with fear. which part of the brain is responsible for processing emotions such as fear and aggression?

Explanation:

1. The medulla oblongata controls involuntary functions like heart - rate and breathing.
2. The reticular activating system filters sensory info and arouses the brain.
3. The cerebellum is key for muscle coordination and balance.
4. The thalamus routes most sensory info except smell.
5. The hypothalamus regulates hunger and other biological drives.
6. The hippocampus is crucial for memory formation and retrieval.
7. The amygdala processes emotions such as fear and aggression.

Answer:

1. Medulla oblongata
2. Reticular activating system
3. Cerebellum
4. Thalamus
5. Hypothalamus
6. Hippocampus
7. Amygdala
