The limbic system is formed by

zoology neural control and coordination parts of the brain brain and its parts brain

  1. The hypothalamus ,epithalamus ,amygdala and hippocampus

  2. Hypothalamus ,amygdala and hippocampus

  3. Corpora quadrigemina and hippocampus

  4. Midbrain and hindbrain

Show answer
Correct Option: A
Explanation:

the limbic system is made up of the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia, and cingulate gyrus.  All the components of the limbic system work together to regulate some of the brain's most important processes.

Which of the following brain structure is not considered to be part of limbic system?

zoology neural control and coordination parts of the brain brain and its parts brain

  1.  Amygdala

  2. Hippocampus

  3. Corpora quadrigemina

  4. Septal nuclei

Show answer
Correct Option: C
Explanation:
  • The limbic system is the portion of the brain that deals with three key functions: emotions, memories, and arousal (or stimulation).
  • The components of the limbic system include Amygdala, Hippocampus, Septal nuclei, thalamus, hypothalamus, basal ganglia.
  • The posterior surface of the adult midbrain is characterized by four elevations collectively called the corpora quadrigemina. It is not a part of the limbic system.
  • Hence the brain structure is not considered to be part of the limbic is Corpora quadrigemina.
  • So, the correct answer is 'Corpora quadrigemina'.
