Question
Your patient has suffered a CVA (cerebral vascular accident) also known as a stroke. Damage to the left hemisphere was the primary effect. Considering the lobes of the brain and lateralization, answer the following questions: 1. Is there a difference between the areas and/or lobes of the cerebrum considering function? 2. Would speech be affected with damage to the left hemisphere? Why or why not. Be sure to detail your answer. 3. Describe the arterial supply of the cerebrum Which blood vessel might be the culprit in the damage to the left hemisphere?Explanation / Answer
Answer
Answer 1)
There are four lobes of cerebrum. All the lobes have distinct functions.
Answer 2)
Yes, speech would be affected by damage to left hemisphere.
Broca area in the frontal lobe of left hemisphere which is responsible for speech production. Broca area is also responsible foe language comprehension.
Wrenicks area present in temporal lobe of left hemisphere is responsible for the comprehension of speech.
As the left hemisphere of cerebrum controls speech and language, damage to left hemisphere leads to impaired speech production and comprehension.
Answer 3)
Arterial supply of cerebrum
- Internal carotid artery supplies anterior cerebrum. It divides into anterior cerebral artery and middle cerebral artery.
- Verebral artery supplies posterior cerebrum usually the occiputal lobe. It joins with basilar artery and divides into posterior cerebral artery.
Middle cerebral artery might be the culprit in the damage to the left hemisphere.
It is the common site for occlusion and occurance of stroke.
The lesions in middle cerebral artery mostly affect the left (dominiant) hemisphere.
