Did you know that our bodies have many, many hormones that carry out processes that range from digestion to sleep?
While I was at NTA, our founder – Gray Graham – gave a great analogy. The endocrine system is like an orchestra. All the instruments must play in harmony or they start to throw each other off.
I’m not very musical – okay, I’m about as musical as a water buffalo -, but I get that you can’t follow the music if the tuba next to you is playing at a different tempo or in the wrong key.
To continue the metaphor, the conductor of this symphony is a part of the brain called the hypothalamus, and the pituitary gland is the first violinist.
Together, they command the entire orchestra to play a particular song, while simultaneously receiving feedback from the instruments to set the right pitch and tone. If the gland is the instrument and the hormone is the sound it produces, just one gland being out of tune will cause disharmony in the entire orchestra. (source)
