Question

Which part of human brain is more develop in comparison of others?

• A. Cerebrum
• B. Cerebellum
• C. Optic lobes
• D. Medulla oblongata

Answer 1

The correct option is A Cerebrum

Cerebrum serves to receive sensory inputs, to bring about integration before commanding voluntary motor responses, to coordinate the activities of another part of the brain, and to carry out higher thought processes for learning, memory, language and speech. Cerebellum serves to coordinate the voluntary movements of skeletal muscles as well as posture, balance and equilibrium. Medulla oblongata consists of reflex centres that control heartbeat, blood vessel diameter and rhythm of breathing as well as other vital functions. Optic lobes serve to receive and interpret the sensory information about sight. Being superior in thinking, speech, memory and language from other animals, the human brain has more developed cerebrum as compared to those of others. This makes option A correct. Medulla, optic lobes and cerebellum perform the vital functions which are more or less common to all animals. Thus, the correct answer is A.
