Question
Which of the following structures or regions is incorrectly paired with its function?
Medulla oblongata: controls respiration and cardiovascular reflexes.
Limbic system: consists of fibre tracts that interconnect different regions of brain; controls movement.
Hypothalamus: production of releasing hormones and regulation of temperature, hunger and thirst.
Corpus callosum: band of fibers connecting left and right cerebral hemispheres.
According to the text, the Limbic system is involved in the regulation of sexual behaviour, expression of emotional reactions (e.g., excitement, pleasure, rage and fear), and motivation . The description 'consists of fibre tracts that interconnect different regions of brain' actually refers to the Pons , and the control of voluntary movements and balance is associated with the Cerebellum and Cerebral cortex . The other pairs are correct: Medulla oblongata controls respiration and cardiovascular reflexes , Hypothalamus regulates temperature, hunger, thirst, and hormones , and Corpus callosum connects the cerebral hemispheres .
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Neural Control and Coordination. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
