Question

Broca’s area situated in:

• A. Inferior frontal gyrus
• B. Superior temporal gyrus
• C. Angular gyrus
• D. None of the above

Answer 1

The Correct Option is A

Broca’s area is a region in the brain that plays a crucial role in the production of language and speech. It is located in the frontal lobe of the cerebral hemisphere and is responsible for motor functions related to speech production. Specifically, Broca's area is situated in the inferior frontal gyrus, which is part of the frontal lobe.

In understanding this, consider the following points:

1. The human brain is divided into two hemispheres, and each hemisphere consists of several lobes, including the frontal lobe.
2. The frontal lobe, located at the front of the brain, is associated with higher cognition, decision-making, and voluntary movement.
3. The inferior frontal gyrus is a part of the frontal lobe and lies beneath the prefrontal cortex.
4. Broca's area, found specifically in the left hemisphere of most people, is located in the posterior part of the inferior frontal gyrus. It is involved in language processing, speech production, and comprehension.

Therefore, among the provided options:

• Inferior frontal gyrus: Correct answer
• Superior temporal gyrus: Area related to auditory processing and also contains Wernicke's area, which is involved in language comprehension.
• Angular gyrus: Involved in various processes related to language, number processing, and spatial cognition.
• None of the above: Incorrect

Thus, the correct answer is that Broca's area is situated in the Inferior frontal gyrus.
