Solution


Q.

Which of the following structures or regions is incorrectly paired with its functions             [2018]
1 Medulla oblongata : Controls respiration and cardiovascular reflexes  
2 Limbic system : Consists of fibre tracts that interconnect different regions of brain, controls movement  
3 Hypothalamus : Production of releasing hormones and regulation of temperature, hunger and thirst  
4 Corpus callosum : Band of fibers connecting left and right cerebral hemispheres  

Ans.

(2)

Certain components of the cerebrum and diencephalon constitute the limbic system. It is sometimes called the emotional brain because it controls emotional behaviour expressed in the form of joy, sorrow, fear, fight, friendship, liking and disliking. It also controls food habits and sex behaviours necessary for survival of the individual.
