Question

Which part of mammalian brain controls the muscular co-ordination?

• A. Cerebrum
• B. Cerebellum
• C. Corpus callosum
• D. Medulla oblongata

Answer 1

The correct option is B Cerebellum

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. It receives sensory impulses about the present position of body parts and motor impulses about the ideal position of the same. Integration of this information ensures smooth, coordinated voluntary movement of skeletal muscles. Corpus callosum is a bridge of white matter that connects two cerebral hemispheres. Medulla oblongata consists of reflex centres that control heartbeat, blood vessel diameter and rhythm of breathing as well as other vital functions. Thus, the correct answer is option B.
