Functions of the frontal lobe
- Personality
- Judgement
- Abstract thinking
- Social behavior
- Broca’s Area (expressive aphasia)
Functions of the parietal lobe
sensory
Functions of the temporal lobe
- Hearing
- Memory
- Speech: Wernicke’s Area (receptive aphasia)
Lesions in this lobe have an increased risk for seizures
Temporal lobe
Functions of the occipital lobe
Vision
Functions of the cerebellum
- Balance/Coordination
2. Major motor/sensory pathways
Important to know about cerebellar lesions
Patients can decline quickly bc it is close to the brain stem
Parts of the brain stem
- Midbrain
- Pons
- Medulla
Functions of the brain stem
- Breathing
- HR
- ANS
- Sleep/Wake functions
- Core functions
- Contains 10 of 12 cranial nerves (III - XII)
The ___ feed the frontal lobes of the brain
Anterior Cerebral Arteries (ACA)
The ___ connects the blood flow between the hemispheres
Anterior Communicating Artery (AcoA)
The ___ feed the parietal and temporal lobes of the brain
Middle Cerebral Arteries (MCA)
The ___ connect the front and back halves of anterior circulation
Posterior Communicating Arteries (PcoA)
The ___ feed the occipital lobes of the brain
Posterior Cerebral Artery (PCA)
Vertebrobasilar circulation is made of up these blood vessels
- Basilar artery (BA)
- Right Vertebral Artery
- Left Vertebral Artery
Vertebrobasilar circulation supplies blood to these areas of the brain
