Answer:
Surface of Cerebral Hemispheres:
The surface of the cerebral hemispheres refers to the outer layer of the brain. It is a highly important part of the brain responsible for various cognitive functions. Let's discuss the given statements one by one.
i. Is made up of the pia matter:
The pia mater is the innermost layer of the meninges, which are the protective membranes surrounding the brain and spinal cord. It is a delicate and thin layer that closely adheres to the surface of the brain. However, it does not make up the surface of the cerebral hemispheres. Therefore, statement i) is incorrect.
ii. Is greatly convoluted and called the cerebral cortex:
The cerebral cortex is the outermost layer of the brain and is highly convoluted. It consists of gray matter and is responsible for higher cognitive functions such as memory, attention, perception, and language. The convolutions, known as gyri and sulci, increase the surface area of the cerebral cortex, allowing for more processing power and a greater number of neurons. Therefore, statement ii) is correct.
Conclusion:
Based on the above explanations, we can conclude that statement i) is incorrect, and statement ii) is correct. Therefore, the correct option is B - Statement i) is wrong, and ii) is correct.
