SGVery Basic

Thyroid = Small Gland in front of neck (weighs less than an ounce).

  • Has 2 lobes that lie along the windpipe (trachea)
  • The lobes and are joined by a band of thyroid tissue (Called the Isthmus).

The Gland
burns energy

make proteins

determines sensitivity to other hormones.

I move beyond old limitations and allow myself to express freely and creatively.3 years ago

SGThe thyroid

The thyroid is in charge of directing the body to:

burn energy,
make proteins,
determine how sensitive the body should be to other hormones.

So imagine the thyroid is a person. Her job description would be to determine what metabolism you shall receive—sort of like a task similar to a boss determining what pay raise an employee would receive.

And like at a job, in some instances, if you do certain things, then you get a better metabolism (just like a good pay raise). In other instances, you may feel like you are just SOL.

I’m not sure about the job of directing the “making of proteins”. That is something I have to learn more about.

I guess Ms. Thyroid is like the leader of the body’s United Nations, because she is in charge of telling the body how to react to all the other hormones, which include:

Thyroid-stimulating hormone (TSH) protein (201) Anterior lobe of pituitary
Follicle-stimulating hormone (FSH) protein (204)
Luteinizing hormone (LH) protein (204)

Retinol Binding Protein 4 protein (~180)
Adiponectin protein (117)

That’s a LOT of hormones to affect if you’re the thyroid. So, if the thyroid is not working properly, different parts of the body can be greatly affected. Sort of like, if the CEO of a company is not competent, she/he can really make a mess of things (using these analogies to drill this information into my head).
