Question 10

The blood-brain barrier protects the brain from harmful substances in the blood,but it also protects the brain from potentially therapeutic chemicals that may reduce the size of brain tumors by killing cancer cells,alleviate depression,and aid in patient recovery from stroke or spinal cord injury.Two methods are currently being rigorously researched to get these helpful chemicals past the blood-brain barrier.The two methods are termed "molecular Trojan Horse" and osmotic "blood-brain barrier disruption." Based on their names,hypothesize how these methods might allow chemicals to pass through the blood-brain barrier.

Question 19

Ginger was a happy,healthy 17-year-old girl.One day while sitting at the kitchen table with her family,she looked up with an odd expression,complained that her head hurt,dropped her fork,and fell off her chair as she lost consciousness.Her father caught her before her head hit the floor.Ginger regained consciousness at the hospital,where it was determined that she had suffered from a ruptured brain aneurysm.An aneurysm results when a blood vessel wall becomes progressively thinner and weaker,and can ultimately rupture,depriving of blood the areas it normally supplies.Sometimes permanent brain damage results.Ginger seems to have all of her normal functions and cognitive abilities,except she cannot see.What areas did the ruptured blood vessel possibly supply with blood? If instead of blindness she could see normally but control of eye movement was abnormal,what areas may have been damaged by loss of blood?

Accepted Answer

For blindness,damaged areas may include
