Question

Sensation from skin are perceived in the cerebrum in
A. Occipital lobe
B. Temporal lobe
C. Parietal lobe
D. Frontal lobe

Answer 1

The human brain consists of the cerebrum, cerebellum, and medulla oblongata. The cerebrum is divided into lobes. They are the frontal lobe, temporal lobe, parietal lobe, occipital lobe, limbic lobe, and insular cortex. The lobes of the brain are related to different brain functions.

Complete answer:
-Occipital lobe: Incorrect answer
The occipital lobe is the visual processing center containing most of the visual cortex. Other regions in this lobe also help in visuospatial processing, color differentiation, and motion perception.
-Temporal lobe: Incorrect answer
The temporal lobe lies beneath the cerebral hemispheres. It is involved in the retention of visual memories, language comprehension, and emotional association. However, it plays an important role in auditory processing and preserving long-term memory.
-Parietal lobe: Correct answer
The parietal lobe is situated behind the frontal lobe. Although it is important for language processing, the parietal lobe is the area of the brain responsible for spatial sense and navigation and the main area for the sense of touch. Signals perceived by the touch, temperature, and pain receptors of the skin move to the thalamus from which they move to the parietal lobe.
-Frontal lobe: Incorrect answer
The frontal lobe is located in front of the cerebral hemispheres. This area of the brain controls the voluntary movements of the body. It also enables thinking and reasoning as it is associated with the neurotransmitter, dopamine. Thus enabling the individual to be attentive and have a sharp short-term memory. It inhibits the relay of any sensory information from the thalamus.

Hence, the correct answer is option (C).

Note: Damage to the lobes may have serious clinical implications. For example, damage to the frontal lobe can lead to partial or complete loss of movement, difficulty in speech, and retention of memory.
