Question 6

What are lobes of the brain?

Answer 6

areas of the cerebral cortex, location and primary function, each with a specialty

Question 7

Frontal lobe

Answer 7

located in the front of the brain, associated with reasoning, motor skills, higher level cognition and expressive language

Question 8

Prefrontal cortex

Answer 8

implicated in planning complex cognitive, behavioral, personality, expression, decision making

Question 9

Motor cortex

Answer 9

receives info from multiple lobes, utilizes the info to carry out body movements

Question 10

Broca’s Area

Answer 10

Located in the lower portion of the frontal lobe
Controls speech production and language comprehension

Question 11

Parietal lobes

Answer 11

Located at the top and back of each cerebral hemisphere
centers for processing sensory signals

Question 12

Somatosensory cortex

Answer 12

receives and processes sensory info from the entire body

Question 13

Occipital lobe

Answer 13

located at the rear
Contains the visual centers of the brain

Question 14

Temporal lobe

Answer 14

responsible for the sense of hearing and meaning of speech

Question 15

Wernicke’s Area

located in the temporal lope
responsible for the comprehension of speech

Question 16

Brainstem

Answer 16

most primitives’ part of the brain
Base of brain connected to the spinal cord

Question 17

Medulla Oblongata

Answer 17

located at the top of the spinal cord
controls life sustaining functions like breathing and heart rate

Question 18

Pons

Answer 18

larger swelling part above the medulla on the brainstem
connects top of brain to bottom of brain

Question 19

Cerebellum

Answer 19

processing sensory input, coordinating movement output and balance and enabling nonverbal learning and memory

Question 20

Thalamus

Answer 20

processes and transmits movement and sensory info to sensory receiving areas in the cortex

Question 21

Reticular formation

Answer 21

neuron network extending from the spinal cord right up through the thalamus and controls arousal
- helps multitasking
- filters incoming stimuli

Question 22

Limbic system

Answer 22

Network of structures located beneath the cerebral cortex
includes the Hypothalamus, Hippocampus, and Amygdala

Question 23

Hypothalamus

Answer 23

Connects with multiple parts of the brain
controls hunger, thirst, emotions

Question 24

Hippocampus

Answer 24

plays a critical role in the formation, organization, and storage of new memories as well

Question 25

Amygdala

Answer 25

linked to emotions of aggression and fear
