Question

In cerebrum, auditory area occurs in
(A) Frontal lobe
(B) Parietal lobe
(C) Temporal lobe
(D) Occipital lobe

Answer 1

Hint: Forebrain forms the major part of the brain. It is also known as prosencephalon. This part of the brain controls temperature of the body, eating, sleeping, some of the reproductive functions, and conveying of emotions etc. The forebrain is divided into cerebrum, thalamus and hypothalamus.

Complete Answer:
Cerebrum forms the upper most and major part of the brain. Cerebrum is separated into two hemispheres and these two hemispheres are joined by means of the nerve fibers called corpus callosum. It is covered by the layer of grey matter which is the cerebral cortex. The cerebral cortex has four lobes in it. It includes frontal, parietal, temporal and occipital lobe.

Frontal lobe: This lobe controls the memory and emotions, cognitive skills, memory, language, sexual behaviors etc.

Parietal lobe: Located in the upper back of the brain. It processes sensory information mainly the information from sense organs like taste, temperature and touch.

Occipital lobe: It processes the signal from the eyes and visual processing. It is used for face or object recognition, color determination and memory formation.

Temporal lobe: In the cerebrum, the auditory area occurs in the temporal lobe. Its main responsibility and function is to control the hearing ability and to process the sound that is obtained from the inner ear and convey it to the brain.

Thus, the option (C) is correct.

Note: Cerebrum is also known as telencephalon. Its function is necessary for the survival part of all the organism. The main function of the cerebrum is to receive and control signals from the sensory organs like eye, ear, skin, nose etc.
