[Solved] While TIAs Often Do Not Have Long-Term Effects, They Are

 A balloon-like bulge in an artery is known as a(n) A) aneurysm. B) embolism. C) thrombosis. D) cerebrovascular accident (CVA).

 A cerebral hemorrhage A) usually does not cause much damage. B) produces milder symptoms than ischemia. C) usually does not produce noticeable behavioral symptoms. D) is frequently fatal due to interfering with the blood supply to neurons and leading to neuron dehydration.

 The area of neural tissue that dies following a stroke or other interruption of cerebral blood flow is known as the A) infarct. B) aneurysm. C) thrombosis. D) embolism.

 An infarct of brain tissue A) seldom produces any noticeable symptoms. B) always triggers unconsciousness or coma. C) contributes to the development of epilepsy. D) produces different symptoms that depend on the size and location.

 Transient ischemic attacks (TIAs) A) produce symptoms of stroke lasting less than 24 hours. B) produce very mild stroke symptoms that last indefinitely. C) are typically fatal within a few hours. D) are very common and do not require medical treatment.

 A thrombosis is A) a blockage resulting from material that doesn't move from its point of origin. B) a blockage resulting from material that travels to smaller diameter blood vessels until it has to stop. C) bleeding in the brain. D) an area of dead neurons.

 An embolism is A) a blockage resulting from material that doesn't move from its point of origin. B) a blockage resulting from material that travels to smaller diameter blood vessels until it has to stop. C) bleeding in the brain. D) an area of dead neurons.

 While a large stroke can cause long-term damage, multiple small strokes A) typically are no cause for concern. B) are not predictive of later larger strokes. C) can also produce significant damage. D) do not produce true infarcts.

 Following ischemia, neural damage is found A) equally distributed throughout the brain. B) primarily in the hippocampus and in middle layers of the cortex. C) primarily in the hippocampus and inner layers of the cortex. D) primarily in subcortical areas.

 Olney's concept of excitotoxicity suggests that most neural death in ischemia is due to A) excess cholinergic activity. B) insufficient gamma-aminobutyric acid (GABA) activity. C) insufficient glutamate activity. D) excess glutamate activity.
