Question

office hours. You will present this on your assigned day to the lab class or during instructor CRITICAL THINKING Complete the following scenario and explain your reasoning by using complete sentences and providing data where necessary. Answers must be typed A 39-year-old female was involved in a bus crash. On scene she was unconscious with cuts on her arms, face, and scalp. She gained consciousness on the way to the hospital and Paramedics observed muscle weakness in her right hand with a near complete paralysis of the right upper extremity and a partial paralysis of the right lower extremity. A head CT revealed an acute subdural hematoma and an extensive subarachnoid hemorrhage. Doctors noted she coul commands, but had difficulty speaking in complete sentences. Surgery to remove the clots was performed immediately and significant improvement was seen two weeks later in follow-up appointments. was agitated and combative. 1. Based on the observed signs, which of the four major regions of the brain were affected? What evidence did you use to determine this? 2. Which side of the brain was involved in the injury? What evidence did you use to determine this? 3. What specific parts of the brain identified in question 1 are being affected by the injury to cause the muscle weakness and language problems? Relative to the meninges, describe the location of the bleeding revealed on the CT scan. 4.

Answer 1

1Cerebrum,Cerebellum ,temboral lobe and Amygdala .All the other reasons for chosing the concerned region is answered in the following questions.In the above mention situation patient became agitated and combatative .This is becauseanger agitation starts with the amygdala stimulating the hypothalamus.That is why people with damage to this area often have trouble controlling their emotions ,especially anger and aggression.

2In this case since the paralysis is on the right side of the body,the left hemisphere might have been affected.Because cerebrum is divided into right and left hemispheres .the left half controls the right side of the body and the right half controls the left side of the body.

3When the stationary head is suddenly accelerated from a blow or upon hitting on a floor the brain goes into a violent mostly sagittal ,but also side-to-side and swirling motion and result in stretching of axons,tears blood vessels and damages the surface of the brain.Temporal lobes might have been affected as it is important for perception.wernickes area-speech comprehension is located in temporal lobe which is in the leftside of the brain.Cerebellum is also affected as it regulates body movements,balance,smooth movement of voluntary muscles and an injury to it result in muscle weakness.
