20) 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?
