motor cortex

Answer 11

strip of cortex involved in planning and coordinating movement

Question 12

occipital lobe

Answer 12

part of the cerebral cortex associated with visual processing; contains the primary visual cortex

Question 13

parietal lobe

Answer 13

part of the cerebral cortex involved in processing various sensory and perceptual information; contains the primary somatosensory cortex

Question 14

prefrontal cortex

Answer 14

area in the frontal lobe responsible for higher-level cognitive functioning

Question 15

somatosensory cortex

Answer 15

essential for processing sensory information from across the body, such as touch, temperature, and pain

Question 16

temporal lobe

Answer 16

part of cerebral cortex associated with hearing, memory, emotion, and some aspects of language; contains primary auditory cortex

Question 17

Wernicke’s area

Answer 17

important for speech comprehension

Question 18

amygdala

Answer 18

structure in the limbic system involved in our experience of emotion and tying emotional meaning to our memories

Question 19

cerebellum

Answer 19

hindbrain structure that controls our balance, coordination, movement, and motor skills, and it is thought to be important in processing some types of memory

Question 20

hindbrain

Answer 20

division of the brain containing the medulla, pons, and cerebellum

Question 21

hippocampus

Answer 21

structure in the temporal lobe associated with learning and memory

Question 22

hypothalamus

Answer 22

forebrain structure that regulates sexual motivation and behavior and a number of homeostatic processes; serves as an interface between the nervous system and the endocrine system

Question 23

limbic system

Answer 23

collection of structures involved in processing emotion and memory

Question 24

medulla

Answer 24

hindbrain structure that controls automated processes like breathing, blood pressure, and heart rate

Question 25

midbrain

Answer 25

division of the brain located between the forebrain and the hindbrain; contains the reticular formation

Question 26

pons

Answer 26

hindbrain structure that connects the brain and spinal cord; involved in regulating brain activity during sleep

Question 27

reticular formation

Answer 27

midbrain structure important in regulating the sleep/wake cycle, arousal, alertness, and motor activity

Question 28

thalamus

Answer 28

sensory relay for the brain

Question 29

ventral tegmental area (VTA)

Answer 29

midbrain structure where dopamine is produced: associated with mood, reward, and addiction

Question 30

brain stem

Answer 30

the central trunk of the mammalian brain, consisting of the medulla oblongata, pons, and midbrain, and continuing downward to form the spinal cord
