Which brain area is known as the motor speech area?

• A. Broca's area
• B. Wernicke's area
• C. Primary auditory cortex
• D. Primary visual cortex

Answer: (A)

The brain region responsible for producing speech movements is Broca's area. It sits in the left frontal lobe and coordinates the muscles involved in speaking—like the lips, tongue, jaw, and larynx—to shape fluent, purposeful speech. When this area is impaired, speech becomes slow and effortful, a pattern known as Broca's aphasia, while comprehension is relatively preserved, highlighting its role in motor planning for speech rather than language understanding. In contrast, Wernicke's area handles language comprehension, the primary auditory cortex processes sounds, and the primary visual cortex handles vision, so they are related to other aspects of communication and perception.
