Question

Which of the following is affected by injury to Broca's area of cerebrum?

• A. Vision
• B. Speech
• C. Hearing
• D. Smell

Hint:

Broca's aphasia results from damage to the Broca's area, impairing speech production while comprehension often remains intact.

Answer 1

The Correct Option is B

Step 1: Understanding Broca's area.
Broca's area, located in the left hemisphere of the brain, is primarily responsible for speech production. Injury to this area results in difficulty speaking, a condition known as Broca's aphasia.
Step 2: Analyzing the options.
(A) Vision: Incorrect, vision is processed by the occipital lobe, not Broca's area.
(B) Speech: Correct, damage to Broca's area impairs speech production.
(C) Hearing: Incorrect, hearing is processed by the temporal lobe, not Broca's area.
(D) Smell: Incorrect, smell is processed by the olfactory bulb, not Broca's area.
Step 3: Conclusion.
The correct answer is (B) Speech, as Broca's area is critical for speech production.
