What structures are considered part of the limbic system Thi

What structures are considered part of the limbic system? This system is associated with mood and motivational behavior, but these behavioral indices can be expressed as a motor response (fear may make one flee, hunger can lead to opening the refrigerator door, etc.). Outline connections you would allow a response in a limbic structure to be expressed by the motor system.

Solution

Limbic system includes structure such as hippocampus, amygdala,thalamus hypothalamus, basal ganglia, and cingulate gyrus.

This system is that portion of brain that deals with memories, emotions, arousal, mood and stimulations.

The fear and rage responses are produced by stimulation of hypothalamus and amygdala. Thelateral parts of hypothalamus then produce a diffuse sympathetic discharge. This massive sympathetic discharge during stress is called as flight or fright response. It causes release of corticotropin-releasing hormone from para ventricular nuclei of hypothalamus. It mediates endocrine and immune responses.
