Question

The primary visual area is located in
A. Temporal lobe
B. Occipital lobe
C. Frontal lobe
D. Parietal lobe.

Answer 1

Hint: Sense organs are controlled by different lobes of the cerebrum which is the largest part of the brain. It is divided into several lobes. The lobe responsible for vision is located in the posterior part of the cerebrum called the visual cortex.

Complete answer: The brain is an important organ in our body which controls all the voluntary and involuntary movements. The brain has three parts; cerebrum, cerebellum and medulla oblongata. The cerebrum is the largest part of the brain which is associated with the control of consciousness, thought, emotion, sight etc. It is divided into four lobes. The occipital lobe is the most important lobe of the mammalian brain as it contains the visual centre which is situated at the back of the brain.
a) Temporal lobe: It is located on the side of the head around the temples. In this region, the hearing, memory, emotion and language centre are located.
b) Frontal lobe: To the front of the cerebral hemisphere is located the frontal lobe. It controls reasoning, language, motor control, etc.
c) Parietal lobe: It is associated with senses like touch, temperature, etc. and is present behind the frontal lobe.
Thus, the correct answer is option B.

Note: The occipital lobe is the primary visual lobe. Any injury to this area can lead to visual damage like blindness or blind spots. The occipital lobe is located at the back which makes it less vulnerable to injuries. Severe trauma to the brain can only affect the visual cortex.
