Which of the following structures or regions is incorrectly paired with its functions?

1. Medulla oblongata : controls respiration and cardiovascular reflexes.
2. Limbic system : consists of fibre tracts that interconnect different regions of brain; controls movement.
3. Corpus callosum : band of fibers connecting left and right cerebral hemispheres.
4. Hypothalamus : production of releasing hormones and regulation of temperature, hunger and thirst.

Correct answer: Limbic system : consists of fibre tracts that interconnect different regions of brain; controls movement.

Solution

The limbic system is mainly involved in emotion, motivation, and memory, not as a set of fiber tracts connecting brain regions or controlling movement. That description fits the corpus callosum more closely, making option B the incorrect pairing.
