Lang Areas and Blood Supply

Question 1

Which language area is involved in motor speech control/planning and syntax, recieves info from auditory cortex to perform self-monitoring and damage causes non-fluent aphasia

Answer 1

Broca’s Area (Frontal lobe)

Question 2

What are the roles of the frontal lobe?

Answer 2

Motor planning/exceution, self monitoring, decision-making, executive function

Question 3

Which lobe is responsible for memory and recognition of emotions? Which two structures in this lobe are important for language

Answer 3

Parietal
 Supramarginal Gyrus
 Angular Gyrus

Question 4

What role does the Supramarginal Gyrus have in language?

Answer 4

Reading (meaning/phonology), writing (SYMBOLIC integration)

“Oh this scribble means /a/”

Question 5

What role does the Angular Gyrus have in language?

Answer 5

Auditory processing, language comp, abstract thought, reading/writing

Question 6

Which lobe is responsible for Audition, speech comprehension, semantic processing, memory?

Answer 6

Temporal

Question 7

Where is Wernicke’s area and what is it responsible for? What does damage here cause?

Answer 7

Posterior superior temporal gyrus – language comp., verbal memory and analysis of speech sounds (damage = fluent aphasia)

Question 8

What area in the occipital lobe is important for language?

Answer 8

Visual Association area: Language comprehension, verbal memory, analysis of speech sounds

Question 9

Vertebral arteries join at the base of brainstem to form the ______ artery

Answer 9

Basilar

Question 10

The Basilar artery branches into _________ and ________ arteries which supply which brain structures?

Answer 10

which branches into cerebellar and pontine arteries which supply brainstem/cerebellum

Question 11

List the 3 cerebral arteries

Answer 11

1) Anterior Cerebral Artery
2) Middle Cerebral artery
3) Posterior Cerebral Artery:

Question 12

Which brain areas does the Anterior cerebral artery supply?

Answer 12

Supplies medial frontal lobe (corpus collosum and basal ganglia as well)

Question 13

Which brain areas does the Middle cerebral artery supply?

Answer 13

PERISYLVIAN area

Question 14

Which brain areas does the Posterior cerebral artery supply?

Answer 14

Supplies inferior temporal lobes

Question 15

Basilar artery branches bilaterally to the posterior cerebral artery and feeds into the ________ via posterior communicating arteries

Answer 15

circle of willis

Question 16

___________arise from common carotid arteries in the neck and connect directly into the Circle of Willis then branch into ______________

Answer 16

• Internal carotid arteries

- posterior communicating artery

Question 17

___________sits on the ventral surface of the brain and provides a safety mechanism against blockages – alternate routes for blood flow

Answer 17

Circle of willis

Question 18

A stoke affecting the ________ cerebral artery is most likely to cause language issues

Answer 18

Middle (so MCA strokes)

Question 19

Posterior MCA stroke most likely causes?

Answer 19

language comprehension issues (more Wernicke’s area)

Question 20

ANterior MCA stroke most likely causes?

Answer 20

telegraphic speech (more Broca’s area)

Question 21

Why is the primary somatosensory and primary motor areas important for speech/language?

Answer 21

Because they control sensation and movement of lips, mouth and tongue (inferior parts of each)

Question 22

List the 4 deep brain structures and their functions.

Answer 22

• Basal ganglia: motor control, learning
• Thalamus: sensory relay center
• Hippocampus: memory formation/retrieval, learning
• Amygdala: emotions, memory, fear, learning

Question 23

The perisylvian language areas is supplied by which artery?

Answer 23

Middle cerebral

Question 24

Generally speaking in terms of language funcrion, the perisylvian area controls _________ processes and pulls ________info from other areas of the brain

Answer 24

Phonological

Semantic

Question 25

What 2 pairs of arteries supply the brain?

Answer 25

Vertebral and Internal carotid arteries

Question 26

Which lobe is responsible for Sensory integration, spatial orientation, memory, recognition/expression of emotion

Answer 26

Parietal

Question 27

Damage to what two areas can lead to apraxia?

Answer 27

Premotor and supplementary motor cortex

Question 28

Damage to the association areas leads to what?

Answer 28

reading (alexia), writing (agraphia), arithmetic (acalculia)
