Cerebrum : Cerebrum is divided into 5 lobes (a) frontal (b) parietal, (c) occipital, (d) temporal and (e) Insula. A lobe called insula is hidden as it lies deep in the sylvian fissure. The cerebral hemisphere are separated from olfactory lobes by rhinal fissure. The median fissure divides the cerebrum into a right and a left cerebral hemisphere. cerebrum is the controller of your activities. 

Control of Voluntary Activities in the Body
- Cerebrum
The cerebrum is the largest part of the brain and is responsible for controlling voluntary activities in the body. It is divided into two hemispheres, each with four lobes that control different functions such as movement, speech, and memory. The cerebrum processes sensory information and sends signals to the rest of the body to carry out voluntary actions.
- Role in Motor Coordination
The cerebrum plays a crucial role in motor coordination, which involves the planning, initiation, and execution of voluntary movements. It receives input from other areas of the brain, such as the cerebellum and basal ganglia, to coordinate smooth and precise movements.
- Integration of Sensory Information
The cerebrum integrates sensory information from the environment and the body to guide voluntary actions. It processes visual, auditory, and tactile inputs to make decisions about how to respond to stimuli and carry out appropriate movements.
- Higher Cognitive Functions
In addition to controlling voluntary movements, the cerebrum is also involved in higher cognitive functions such as problem-solving, decision-making, and emotional processing. It enables us to think, reason, and plan ahead, allowing for complex behaviors and actions.
- Overall Control Center
Overall, the cerebrum acts as the control center for voluntary activities in the body, coordinating various brain regions and neural pathways to carry out precise and coordinated movements. Its complex structure and functions make it essential for our ability to interact with the world and perform everyday tasks.
