is responsible for brining her back to a normal state of arousal?

A. sympathetic nervous systemB. somatic nervous systemC. parasympathetic nervous systemD. skeletal nervous system

Discussion Question

Your best friends invite you over for pizza and a friendly game of cards.

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.
