Cerebrum Cerebrum is the largest part of the human brain . It controls: Thinking Intelligence Memory Learning Speech Voluntary actions Cerebral Hemispheres A deep groove divides the cerebrum into: Left cerebral hemisphere Right cerebral hemisphere Corpus Callosum Both hemispheres are connected by nerve fibres called: Corpus callosum It allows communication between the two hemispheres. Cerebral Cortex Outer layer of cerebrum is called the cerebral cortex . It is highly folded to increase surface area. It appears grey due to presence of neuron cell bodies. Therefore, it is called Grey Matter . Functions of Cerebral Cortex It contains: Motor areas → control voluntary movements. Sensory areas → receive sensory impulses. Association areas → involved in: Memory Inte...

This is called coordination . What is Coordination? Definition Coordination means: Two or more organs work together They help each other perform functions properly It maintains balance inside body ( homeostasis ) Homeostasis Maintenance of constant internal environment Example: Normal body temperature Normal blood pressure Proper oxygen level Example of Coordination During Exercise When we do physical exercise: Step 1: Muscle activity increases Muscles need more energy Step 2: Oxygen demand increases More oxygen is required to produce energy Step 3: Respiration rate increases Lungs work faster Breathing rate increases Step 4: Heartbeat increases Heart pumps blood faster Step 5: Blood flow incr...
