Visual association area, auditory association area, Wernickes area and Brocas area of the Brain are concerned with reception, formulation and expression components of speech.Wernicks areao It is located in the posterior end of superior temporal gyrus.o It is the site of integration of secondary somatic, Auditory and visual areas.o 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 part of the speech and sends signals to the Brocas area via arcuate faciculus.o So, Wernicke 9s area is concerned with comprehension.o Lesion to this area results in sensory fluent aphasia.Brocas area Area 441o Brocas area is located in the inferior frontal gyrus.o It constitutes the center for motor part of speech. It receives information from Wernickes area and sends it to the motor cortex concerned with control of larynx, lips and tongue for spoken speech and fingers for written speech.o Lesions of the Brocas area produce an inability to express onself by spoken speech called motor aphasia or nonfluent aphasia.Interpretation of words, read or heard By secondary visual or auditary areas Formulation of ideas which is to be expressed in speechi.e. Words are planned in Wernickes area Plan is passedThrough arcuate fasciculusSentence is formulated in Brocas areaIdea is expressed in sentence Transmitted to motor cortex for actual external expression by movements of finger in written speech or larynx, tongue, lips for spoken speech
