hypothalamus

The hypothalamus could be considered the most "primitive" aspect of the limbic system, though in fact the functioning of this sexually dimorphic structure is exceedingly complex. The hypothalamus regulates internal homeostasis including the experience of hunger and thirst, can trigger rudimentary sexual behaviors or generate feelings of extreme rage or pleasure. In conjunction with the pituitary the hypothalamus is a major manufacturer/secretor of hormones and other bodily humors, including those involved in the stress response and feelings of depression.

My stomach was in a tight knot. Not because of the uneven dirt road his small truck tried to handle and not because of my kid's bellowing questions from the backseat.

I looked over at my husband from the corner of my eyes and asked myself if I truly knew him. My partner and father of my two children.
