Which statement gives the best explanation of division of work in the brain?
Answer and explanation
Correct answer: Cerebrum is linked with thinking, cerebellum with balance and medulla with involuntary actions
The brain shows division of labour because its regions have specialised but coordinated functions. The cerebrum supports conscious thought, memory and voluntary activities; the cerebellum helps coordinate muscular activity and maintain posture and balance; and the medulla regulates important involuntary actions such as breathing and heartbeat. Therefore option A is correct. The other options wrongly assign blood filtration, hormone secretion or memory to these brain regions.
