CBSE Class 10 Science 2019 · Paper 31/3/1 · Question 11
List in tabular form three distinguishing features between cerebrum and cerebellum.
Answer
The cerebrum (fore-brain) is the thinking part that starts voluntary actions; the cerebellum (hind-brain) keeps posture and balance and makes actions precise.
(i) Part of the brain: The cerebrum is the main part of the fore-brain (the largest part of the brain), while the cerebellum is a part of the hind-brain.
(ii) Main function: The cerebrum is the main thinking part of the brain, the seat of intelligence, memory and reasoning, while the cerebellum maintains the posture and balance (equilibrium) of the body.
(iii) Voluntary actions: The cerebrum initiates voluntary actions, while the cerebellum makes them precise, as in walking in a straight line, riding a bicycle or picking up a pencil.
