The largest part of forebrain which controls the intelligence, emotions and skeletal muscles is classified as?
Correct answer: D. Cerebrum
- A. Hypothalamus
- B. Thalamus
- C. Cerebellum
- D. Cerebrum
Explanation
The explanation for this question is as follow: Cerebrum is the largest part of the brain and is divided into two halves, called cerebral hemispheres. These halves communicate with each other by means of a large band of axons, called corpus callosum.Tens of billions of neurons are packed into this part. The outer region, the cerebral cortex, forms folds called convolutions, which greatly increase its surface area. This part receives sensory information, processes it, stores some in memory for future use, directs voluntary movements, and is responsible for the poorly understood process that we call thinking.The cerebral cortex contains primary sensory areas where signals originating in sensory organs such as eyes and ears are received and converted into subjective impressions, such as light and sound. Nearby association areas interpret this information. This area is also involved in speech and also receives and interprets sensations of touch from all parts of the body. This area is also a centre for sending impulses to voluntary muscles, controlling movements. This is also involved in intelligence, reasoning and judgement.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
