I. It contains association areas that are responsible for complex functions like intersensory associations, memory and communication.
II. It controls osmolarity of body fluids, urges for eating and drinking.
III. It is involved in the regulation of sexual behaviour, expression of emotional reactions.
IV. It controls cardio-vascular reflexes and gastric secretions.
Options:
Answer:
Solution:
Cerebral cortex contains association areas, are responsible for complex functions like intersensory associations, memory and communication.
Hypothalamus control body temperature, osmolarity of body fluids, urge for eating and drinking. The inner parts of cerebral hemispheres and a group of associated deep structures like amygdala, hippocampus, etc., form a complex structure called the limbic lobe or limbic system. Along with the hypothalamus, it is involved in the regulation of sexual behaviour, expression of emotional reactions (e.g., excitement, pleasure, rage and fear), and motivation.
The medulla of the brain is connected to the spinal cord. The medulla contains centres which control respiration, cardiovascular reflexes and gastric secretions.
