Question

Sensory speech areas occurs in
A. Parietal lobe
B. Parietal lobe and partly in temporal lobe
C. Temporal lobe
D. Temporal and occipital lobes

Answer 1

Hint: Sensory speech area is a part of the cerebrum. It is responsible for the speech and language process in human beings.

Complete answer:
The central organ of the human nervous system is the human brain and along with the spinal cord, it forms the central nervous system of the human body. The human brain is composed of the cerebrum, brainstem, and cerebellum. The cerebrum forms the largest part of the brain and further divided into two hemispheres called the left hemisphere and right hemisphere by the corpus callosum. The cerebrum is divided into six lobes: frontal lobe, parietal lobe, occipital lobe, temporal lobe, and limbic lobe. Depending upon the functions the cerebral cortex is divided into sensory, motor, and associative areas. Sensory information is received and processed in the sensory area of the brain. information about temperature, taste, touch, and movement is processed by the parietal lobe whereas the occipital lobe is responsible for vision. processes like memories, integrating them with sensations of taste, sound, sight, and touch is done by the temporal lobe. Wernicke’s area, which is the sensory speech area is found in the temporal lobe of the cerebrum. So, the sensory speech area is located in the temporal lobe.

Therefore, option C is the correct answer.

Note: The area associated with speech production is Broca’s area placed in the frontal lobe of the hemisphere whereas Wernicke's area in the temporal lobe is responsible for language development and comprehension of speech. Damage to Wernicke’s area causes Wernicke’s aphasia which is a language disorder.
