Answer 1

The four important parts involves are: Limbic, hypothalamus, theamygdala, and hippocampuses.

Limbic: the role of limbic system is very important; it is a set of structures in the brain and it covers hypothalamus/hippocampus, as well as amygdale. Actions such as hunger, thirst, and responses to pain are being controlled by hypothalamus . It also oversees the bodily changes like breathing, blood pressure as well as arousal in response to emotional changed.

Data in put receives and instructions are being sent out for the rest of the body through hypothalamus. It carries its’ change of body function through the blood stream; a goose bump is one of the examples of hypothalamus being at work.

The amygdala: has a shape of an almond; and is a mass of neurons in each part of brain; the brain posses two the amygdala. There is right one and the left one. In animals when the theamygdala is stimulated electronically; they get very aggressive. But when the amygdala is removed; animals becomes very tame and no longer respond to things that would caused anger in him before.

The last one is hippocampus: It resembles two horns that curve back from amygdala. The hippocampus is very important for making, maintaining, and storing your memories. It does send the information from the senses.
