Which of the following structures or regions is incorrectly paired with its functions?
Answer: (B) Limbic system : consists of fibre tracts that interconnect different regions of brain; controls movement.. Answer: (b) Limbic system: Forebrain, controls the movement.
- A.Hypothalamus : production of releasing hormones and regulation of temperature, hunger and thirst.
- B.Limbic system : consists of fibre tracts that interconnect different regions of brain; controls movement.✓
- C.Medulla oblongata : controls respiration and cardiovascular reflexes.
- D.Corpus callosum : band of fibers connecting left and right cerebral hemispheres.
Correct Answer
(B) Limbic system : consists of fibre tracts that interconnect different regions of brain; controls movement.
Solution & Explanation
Answer: (b) Limbic system: Forebrain, controls the movement. Solution: The limbic system does NOT control movement; together with the hypothalamus it regulates sexual behaviour, emotional reactions (excitement, pleasure, rage and fear) and motivation. So pairing the limbic system with 'controls movement' is the incorrect pair. The other listed structure-function pairings are correctly matched.
