Chapter 38, Problem 1TYU

Patients with damage to Wernicke’s area have difficulty

1. A.    coordinating limb movement.
2. B.     generating speech.
3. C.     recognizing faces.
4. D.    understanding language.

Summary Introduction

Introduction:

A part in the cerebral cortex which is responsible for the speaking or writing any language is known as Wernicke’s area. It is present in the posterior part of the brain.

Answer to Problem 1TYU

Correct answer:

The Wernicke’s area is responsible for understanding the language. Therefore, option (d) is correct.

Explanation of Solution

Reason for the correct statement:

The fluency of the words is connected through this Wernicke’s area. If an individual suffers damage in Wernicke’s area, then the affected individual is not able to understand the words and the meaning of sentences properly.

Option (d) is given as “understanding language”.

As “patients with damage to Wernicke’s area have difficulty in understanding language”, it is the right answer.

Hence, option (d) is correct.

Reasons for the incorrect statements:

Option (a) is given as “coordinating limb movement”.

The difficulty in coordinating in the movement of limbs is possible when the damage is in the cerebral hemisphere. So, it is a wrong answer.

Option (b) is given as “generating speech”.

The generation of speech is the final result of the problem in Wernicke’s area in which the understanding of language and sentence framing is difficult. So, it is a wrong answer.

Option (c) is given as “recognizing faces”.

The damage in the area of brain may lead to the situation in which the individual is not able to recognize the faces. So, it is a wrong answer.

Hence, options (a), (b), and (c) are incorrect.

Conclusion

The Wernicke’s area is the part of the brain which controls the language understanding of the individual and make them able communicate by helping in the formation of sentence.
