Her heart immediately begins to race as she withdraws her hand, but soon she realizes that the spider is harmless, and she begins to calm down. Which part of her nervous system is responsible for brining her back to a normal state of arousal? A. B. C.

Describe how the following parts of the brain are involved during your evening of eating pizza, socializing, and playing cards: Broca’s area, hippocampus, hypothalamus, and occipital lobe. • • • • Broca’s area? Hippocampus? Hypothalamus? Occipital lobe? • Broca’s area is involved with socializing and helps everyone talk to one another. • The hippocampus is involved with socializing and helps everyone form immediate and long-term memories of the evening. • The hypothalamus is involved with eating pizza and lets everyone know if they are hungry or full. • The occipital lobe is involved with all aspects because it helps everyone to see the cards, the pizza, and each other.
