C) It provides genetic sequencing data
D) It evaluates only the tissue architecture
Answer: B
Explanation: Immunohistochemistry uses antibodies to detect protein expression patterns that assist in
tumor diagnosis and classification.
14. How does ethical practice impact neuropathology?
A) It eliminates the need for diagnostic tests
B) It ensures proper handling and consent for tissue samples
C) It reduces the workload of the neuropathologist
D) It increases the number of procedures performed
Answer: B
