A. True
B. False

A. True

Explanation:

In our brain, hippocampus, amygdala and hypothalamus together function in a coordinated way and collectively form the limbic system. The structures constituting this limbic system are involved in motivation, emotion, learning, and memory related functions. Both, the endocrine system and the autonomic nervous system are influenced by the limbic system. So whenever we perform well in our exams, the structures constituting the limbic system sends signals to the endocrine system and endorphins are released and as a result of this coordinated hormonal and neural control, we feel great.
