Question

Which part controls the balance of the human body?
(A) Cerebrum
(B) Cerebellum
(C) Optic lobes
(D) Spinal cord

Answer 1

Human body is a complex system among all living organisms. It is composed of living cells and extracellular materials. It is organized into tissues, organs and systems where the brain is the most important organ which helps in controlling the whole human body. It is one of the largest and most complex organs which contains 100 billion nerves that communicate a large number of synapses to produce an external response.

Complete answer:
(A)Cerebrum: Cerebrum is the uppermost part of the brain. It contains two hemispheres called right and left hemispheres split by a central fissure. It contains the major lobes of the brain which are the frontal lobe, parietal lobe, temporal lobe, occipital lobe. These lobes are helpful in the initiation and coordination of movement, temperature, touch, vision, hearing, judgement, reasoning, problem-solving, emotions and learning. It is responsible for receiving and giving meaning to information from the sense organs as well as controlling the body.
(B)Cerebellum: The cerebellum is a major structure of the hindbrain that is located near the brainstem. It receives information from the sensory system, the spinal cord and other parts of the brain and then regulates motor movements. It coordinates voluntary movements such as balance, posture, coordination and speech, resulting in smooth and balanced muscular activity.
(C) Optic lobes: Optic lobe is a part of brain structure involved in vision. The optic lobe of each side is a large and complex extension of the brain, this is the analysis of visual input from the eye as well as having other higher functions related to memory and initiation and control of behaviour. Its neural organization is complex and highly structured.
(D) Spinal cord: The spinal cord is a long, fragile tubelike structure that begins at the end of the brain stem and continues down almost to the bottom of the spine. Together with the brain, they function as the central nervous system (CNS) where it transmits the information from the brain to other parts and vice versa. Here the brain decodes the message and the spinal cord becomes a medium to transmit the decoded message to other parts of the body.

So, option (B) is the correct option.

Note: In above we detailed the part which controls the balance and other parts which are an important part of the brain and nervous system. All these parts are very helpful in transmitting information and controlling human body parts.
