Question

Cerebrovascular Accident Activ... Cerebrovascular Accident (CVA) Activity Precentral Gyrus Central Sulcus Postcentral Gyrus Frontal Lobe -Parietal Lobe Lateral Sulcus Occipital Lobe Temporal Lobe Cerebellum Pons Medulla Oblongata On the areas of the brain labeled, identify the deficit the person would experience if they experienced a CVA in that area of the brain. (Look at handout Brain Function for answers. It will be opened in a week.) 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. Which area of the brain if affected by brain injury would be potentially life threatening?

Answer 1

1.Functions of frontal lobe are involved in the motor function,problem solving, spontaneity,memory, language, initiation, judgemet ,impulses control and social and sexual behavior..Frontal lobe is a full of dopamine sensitive neurons,and they are involved in many tasks like reward,attention ,Short term memory planning and motivation. If Frontal lobe affected by CVA , it causes deficit dopamine sensitive neurons leads to lack of motivation, lack of attention, memory loss and causes depression also .

2. Precentral gyrus is the anatomical location of the primary motor cortex,which is responsible for controlling voluntary motor movement on the body's contra lateral side. If precentral gyrus results in the paralysis of the contralateral side of the body like if precentral gyrus in left side cerebrum affected with CVA ,patient experience right side paralysis.

3.The central sulcus is a prominent land mark of the brain ,separating the parietal lobe from the frontal lobe and the primary motor cortex from the primary somatosensory cortex. If This central sulcus damaged by CVA it leads to sensory motor deficit and causes attention deficit hyperactivity disorder.

4.Damage to post central gyrus cause proprioception, astereognosis,loss of vibratory senses and loss of two point discrimination in the trunk or extremities.

5. And 6. Parietal lobe help to make sense of sensory information,sense of touch,and the part of vision that deals with the location of objects.if stroke hits the left side of the parietal lobe we feel aphasia.if it hits right side deficit will be more cognition,thinking,calculations.
