Which of the following regions of the brain is incorrectly paired with its function?

  1. Corpus callosum - communication between the left and right cerebral cortices
  2. Cerebrum - calculation and contemplation
  3. Medulla oblongata - homeostatic control
  4. Cerebellum - language comprehension

Answer

(4) Cerebellum - language comprehension

Solution

Corpus callosum connects the two cerebral hemispheres. ⇒ correct

As per NCERT, the association areas of the cerebral cortex are responsible for complex functions like intersensory associations, memory and communication. ⇒ cerebrum – calculation, contemplation and language are correct

Medulla oblongata controls respiration, cardiovascular reflexes and gastric secretions (homeostatic control). ⇒ correct

Cerebellum maintains posture, balance and coordination of movements; it does not perform language comprehension.

∴ Cerebellum – language comprehension is incorrectly paired.

Answer: (4)
