The Broca's area and Wernicke's center are the association areas situated in cerebrum. These are related to __________. (a) breathing (b) blind spot (c) memory (d) None of those
Hint: Broca's area is basically the motor speech area whereas Wernicke's area plays a role in understanding speech and writing words.
Complete answer:Broca's area is a region in the frontal lobe of the dominant hemisphere (usually the left) of our brain, with functions linked to the production of speech. It was named in 1861 as the center of speech articulation. It is essentially responsible for controlling the movement of the muscles of the speaking apparatus and related movements of speech involving parts of the body like the tongue, lips, pharynx, and larynx.
Wernicke's area is the region of the brain that is very essential for language development. It is located in the temporal lobe of the brain, on the left side towards the posterior section of the superior temporal gyrus.
This area prominently encircles the auditory cortex on the lateral sulcus, the part of the brain where the temporal lobe and parietal lobe meet and is primarily responsible to comprehend the speech while Broca's area is related to the production of speech. Broca's area and Wernicke's area are joined by a bundle of nerve fibers known as the arcuate fasciculus.
So, the correct option is ‘None of these’.
Note:After reading to speak the word, information must first get to the first visual area. From the primary visual cortex, information is next transmitted to the posterior speech area, including Wernicke's area. Now from the Wernicke's area, information travels to Broca's area, and finally to the primary motor region from where signals are sent to motor muscles involved in the process of speech.
