Closed head injury:
A. involves damage to the cortex, axons, and ventricles.
B. reduces the risk of Alzheimer’s disease.
C. can result in Parkinsonism.
D. involves penetration of an object into brain tissue.
I chose C
agree.
I'm sorry, but the correct answer is A.
A closed head injury refers to an injury that occurs when the head is struck by an external force, causing damage to the brain inside the skull without any penetration of an object into the brain tissue. The options B, C, and D are incorrect because they do not accurately describe a closed head injury.
Option B states that a closed head injury reduces the risk of Alzheimer's disease, which is not true. In fact, there is evidence to suggest that individuals who have experienced a traumatic brain injury, including closed head injuries, may be at greater risk for neurodegenerative disorders like Alzheimer's disease.
Option C states that a closed head injury can result in Parkinsonism, which is also incorrect. Parkinsonism is a syndrome characterized by motor symptoms similar to those seen in Parkinson's disease, but it is not typically associated with closed head injuries.
Option D states that a closed head injury involves penetration of an object into brain tissue. However, as mentioned earlier, a closed head injury does not involve any penetration of an object.
