Choose the combination of statements that are correct for the cerebrum...
Brain has three parts viz. forebrain, mid brain and hind brain.
Cerebrum : It is part of forebrain and largest part of brain. It is divided into two halves called cerebral hemispheres. These halves are connected by a tract of nerve fibers called corpus callosum. It contains major areas seasory and processing.
Hypothalamus : It is part of forebrain and found below thalamus, hence its name. It produces hypothalamic hormones that control secretion of pituitary gland hormones. It also controls body temperature and urge for eating and drinking.
Cerebellum : It is found in hind brain. It is major part involved in coordinating the movements of body. Thus, statements P and S are correct for cerebrum.

Choose the combination of statements that are correct for the cerebrum...
The correct combination of statements for the cerebrum of the human brain is option 'C' (PS).
Explanation:
The cerebrum is the largest part of the human brain and is responsible for many important functions. Let's break down each statement to understand its role in detail:
1. Statement P: It is the largest part of the brain.
- The cerebrum is indeed the largest part of the brain, accounting for about 85% of the brain's weight. It is located in the uppermost region of the brain and is divided into two hemispheres.
2. Statement S: Receives and processes sensory information.
- The cerebrum plays a crucial role in receiving and processing sensory information from various parts of the body. It contains specialized regions called sensory areas that receive information related to touch, vision, hearing, taste, and smell. These sensory areas analyze and interpret the incoming signals, allowing us to perceive and understand our environment.
Therefore, the combination of statements P and S is correct for the cerebrum of the human brain. The cerebrum is both the largest part of the brain and involved in receiving and processing sensory information.
Statements Q and R are incorrect for the cerebrum:
- Statement Q: Controls the pituitary hormone secretion.
- The pituitary gland, which is responsible for hormone secretion, is actually controlled by the hypothalamus, not the cerebrum. The hypothalamus is a small region located below the thalamus and plays a crucial role in regulating hormone production and release from the pituitary gland.
- Statement R: Involved in coordinating the movements of the body.
- The coordination of body movements is primarily controlled by the cerebellum, not the cerebrum. The cerebellum, located at the lower back of the brain, is responsible for maintaining balance, posture, and coordinating voluntary muscle movements.
Therefore, the correct combination of statements for the cerebrum of the human brain is option 'C' (PS). The cerebrum is the largest part of the brain and is involved in receiving and processing sensory information.
