Lang Areas and Blood Supply Flashcards
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
Broca’s Area (Frontal lobe)
What are the roles of the frontal lobe?
Motor planning/exceution, self monitoring, decision-making, executive function
Which lobe is responsible for memory and recognition of emotions? Which two structures in this lobe are important for language
Parietal
Supramarginal Gyrus
Angular Gyrus
What role does the Supramarginal Gyrus have in language?
Reading (meaning/phonology), writing (SYMBOLIC integration)
“Oh this scribble means /a/”
What role does the Angular Gyrus have in language?
Auditory processing, language comp, abstract thought, reading/writing
Which lobe is responsible for Audition, speech comprehension, semantic processing, memory?
Temporal
Where is Wernicke’s area and what is it responsible for? What does damage here cause?
Posterior superior temporal gyrus – language comp., verbal memory and analysis of speech sounds (damage = fluent aphasia)
What area in the occipital lobe is important for language?
Visual Association area: Language comprehension, verbal memory, analysis of speech sounds
Vertebral arteries join at the base of brainstem to form the ______ artery
Basilar
The Basilar artery branches into _________ and ________ arteries which supply which brain structures?
which branches into cerebellar and pontine arteries which supply brainstem/cerebellum
List the 3 cerebral arteries
1) Anterior Cerebral Artery
2) Middle Cerebral artery
3) Posterior Cerebral Artery:
Which brain areas does the Anterior cerebral artery supply?
Supplies medial frontal lobe (corpus collosum and basal ganglia as well)
Which brain areas does the Middle cerebral artery supply?
PERISYLVIAN area
Which brain areas does the Posterior cerebral artery supply?
Supplies inferior temporal lobes
Basilar artery branches bilaterally to the posterior cerebral artery and feeds into the ________ via posterior communicating arteries
circle of willis
___________arise from common carotid arteries in the neck and connect directly into the Circle of Willis then branch into ______________
- Internal carotid arteries
- posterior communicating artery
___________sits on the ventral surface of the brain and provides a safety mechanism against blockages – alternate routes for blood flow
Circle of willis
A stoke affecting the ________ cerebral artery is most likely to cause language issues
Middle (so MCA strokes)
Posterior MCA stroke most likely causes?
language comprehension issues (more Wernicke’s area)
ANterior MCA stroke most likely causes?
telegraphic speech (more Broca’s area)
Why is the primary somatosensory and primary motor areas important for speech/language?
Because they control sensation and movement of lips, mouth and tongue (inferior parts of each)
List the 4 deep brain structures and their functions.
- Basal ganglia: motor control, learning
- Thalamus: sensory relay center
- Hippocampus: memory formation/retrieval, learning
- Amygdala: emotions, memory, fear, learning
The perisylvian language areas is supplied by which artery?
Middle cerebral
Generally speaking in terms of language funcrion, the perisylvian area controls _________ processes and pulls ________info from other areas of the brain
Phonological
Semantic
What 2 pairs of arteries supply the brain?
Vertebral and Internal carotid arteries
Which lobe is responsible for Sensory integration, spatial orientation, memory, recognition/expression of emotion
Parietal
Damage to what two areas can lead to apraxia?
Premotor and supplementary motor cortex
Damage to the association areas leads to what?
reading (alexia), writing (agraphia), arithmetic (acalculia)
difficulty with L and R
