Question

Which function will be lost due to damage to the occipital lobe?
A. Hearing
B. Speech
C. Vision
D. Memory

Answer 1

Human body possesses different kinds of sensory organs which receive stimulus from the external environment and respond according to it. The name of such sensory organs are ear, eyes, tongue, skin, and nose; they perform a different function.

Complete answer:
Occipital lobe belongs to the cerebral cortex in the brain and it is the place of the visual processing center and contains an anatomical region of the visual cortex.
The occipital lobe is one of the four major lobes of the cerebral cortex of the brain, and two occipital lobes are the smallest of four pair lobes, that present in the rearmost portion of the skull and it is the part of the posterior cerebrum. The occipital lobes divided into different functional visual areas. If the occipital lobe is damaged that results in damage in the vision. If one of the occipital lobes is damaged, then it causes homonymous hemianopia vision loss and occipital lesions cause visual hallucinations.
A. Hearing:- This process is related to the temporal lobe of the brain which contains the primary auditory cortex. The auditory cortex receives auditory information from the ears and other secondary areas and then processes the information to make it understandable.
B. Speech:- This process is also associated with the temporal lobe of the brain, the language, and is the process by the left hemisphere of the brain which is a dominant hemisphere.
D. Memory:- Memory process is also related to the temporal lobe of the brain, this temporal lobe controls memory, speech, and comprehension.
Hence the correct option is C.

Note: The right hemisphere region of the brain plays a significant role in the interpretation of visual information and spatial processing apart from the occipital lobe, which is the major part that performs the visual task.
