The middle cerebral artery (MCA) is the most common of the cerebral arteries to be affected by stroke. A patient is sent in to emergency with difficulty speaking and weakness in her right arm. She is able to follow instructions, but is unable to speak. When the doctor asks her to hold both of her arms up in front of her, her Right arm slowly drifts back down to her side. What SPECIFIC area of the brain must be affected in order to cause the weakness
