1. Hindbrain
2. Midbrain
3. Forebrain

Question 16

Answer 16

• pons
• medulla
• midbrain
• spinal cord

Question 17

Answer 17

the pons

Question 18

What area of the brain controls respiratory rhythmicity, vomiting, coughing, sneezing and swallowing?

Answer 18

the medulla oblongata

Question 19

What is the cerebellum responsible for?

Answer 19

complex movement, hand/eye coordination

Question 20

What is the midbrain?

Answer 20

the is the audio/visual relay station that contains much of the reticulating activating system (RAS - arousal, wakefulness)

Question 21

What is the relay processing center for sensory information?

Answer 21

the thalamus

Question 22

What does the hypothalamus control?

Answer 22

• emotion
• hormone production
• sleep/wake cycles

Question 23

What structures make up the “diencephalon?”

Answer 23

thalamus + hypothalamus

Question 24

What connects the two hemispheres of the brain?

Answer 24

the corpus collosum

Question 25

What is the nucleus accumbens?

Answer 25

the "pleasure center" of the brain

Question 26

What is the "arcuate fasciculus?"

Answer 26

a bundle of axons that connects Broca's area to Wernicke's area

Question 27

What is the function of the lateral hypothalamus?

Answer 27

causes you to feel hungry Lateral Hypothalamus: L = "Let's eat!"

Question 28

What would happen if the lateral hypothalamus were destroyed?

Answer 28

you would no longer have anything to signal that you are hungry, so you would starve to death

Question 29

What is the function of the ventromedial hypothalamus?

Answer 29

causes you to feel full Ventromedial Hypothalamus: V = "I'm Very Very full!"

Question 30

What would happen if the ventromedial hypothalamus were destroyed?

Answer 30

you would no longer have anything to signal that you are full, so you would continue to overeat
