brain dysfunctions
homeostatic imbalance 7.7 brain dysfunctions are unbelievably varied. we discuss some of them—the terrible three—in a closer look (pp 252 - 253), and we will discuss developmental problems in the final section of this chapter. here, we will focus on traumatic brain injuries and (1 ) accidents. we describe techniques used to diagnose many brain disorders in a closer look later in the chapter (pp 270 - 271)
traumatic brain injuries head injuries are a leading cause of accidental death in the united states. consider, for example, what happens if you crash into the rear end of another car. if youre not wearing a seatbelt, your head will jerk forward and then violently stop as it hits the windshield. brain trauma is caused not only by (2 ) at the site of the blow, but also by the effect of the ricocheting brain hitting the opposite end of the skull.
a concussion occurs when brain injury is slight. the victim may be dizzy, “see stars,” or lose consciousness briefly, but typically little permanent brain damage occurs. a brain contusion results from marked tissue (3 ). if the cerebral cortex is injured, the individual may remain conscious, but severe brain stem contusions always result in a coma lasting from hours to a lifetime due to injury to the reticular activating system.
after head blows, death may result from (4 ) hemorrhage (bleeding from ruptured vessels) or cerebral edema (swelling of the brain due to inflammatory response to injury). individuals who are initially alert and lucid following head trauma and then begin to deteriorate neurologically are most likely (5 ) or suffering the delayed consequences of edema, both of which compress vital brain tissue.

Explanation:

1. The text focuses on brain - related issues, and "intracranial" accidents are relevant to brain dysfunctions.
2. Brain trauma is caused by "hemorrhaging" at the site of the blow and the ricochet effect.
3. A brain contusion results from tissue "injury".
4. After head blows, death can result from "intracranial" hemorrhage.
5. Individuals deteriorating neurologically are likely suffering from "hemorrhaging" or edema - related issues.

Answer:

1. intracranial; 2. hemorrhaging; 3. injury; 4. intracranial; 5. hemorrhaging
