<prompt> Wernickes area is located in ?Inferior frontal gyrusSuperior temporal gyrusInferior temporal gyrusCingulate gyrus  <response>: Ans. is b i.e., Superior temporal gyrus Wernicks areaIt is located in the posterior end of superior temporal gyrus. It is the site of integration of secondary somatic, Auditory and visual areas. In response to words heard or read and interpreted by the secondary auditory or visual sensory areas, the Wernickes area formulate ideas words are planned for expressive pa of the speech and sends signals to the Brocas area arcuate faciculus. So, Wernickes area is concerned with comprehension. Lesion to this area results in sensory fluent aphasia.Brocas area Area 44Brocas area is located in the inferior frontal gyrus. It constitutes the center for motor pa of speech. It receives information from Wernickes area and sends it to the motor coex concerned with control of larynx, lips and tongue for spoken speech and fingers for written speech. Lesions of the Brocas area produce an inability to express onself by spoken speech called motor aphasia or nonfluent aphasia.
