Anatomy of Hair. A diagram of hair anatomy appears relatively straightforward, but it's actually one of the most complicated structures in the body.

Because it affects virtually every organ in our bodies, the thyroid gland can be linked to modest changes in body weight and energy levels. The thyroid gland is an endocrine gland located in the front of our necks. It stores and produces hormones that affect the function of virtually every organ in our bodies.
