Anatomy of Hair. A diagram of hair anatomy appears relatively straightforward, but it's actually one of the most complicated structures in the body. Hair is made up the two separate structures: the hair follicle, which exists below the skin, and the hair shaft, which is the hair we see. The hair follicle is the living part of the hair.
How hypothyroidism negatively affects your stomach acid levels. Just as hypothyroidism can result in the drying out of your skin and hair, it also seems to lower the levels of stomach acid in many thyroid patients, possibly by lowering your amount of parietel cells or lowering their ability to produce gastric acid, aka hypochlorhydria.
The purpose of your thyroid gland is to make, store, and release thyroid hormones into your blood. These hormones, which are also referred to as T3 (liothyronine) and T4 (levothyroxine), affect almost every cell in your body, and help control your bodyâs functions.t does this by releasing more thyroid-stimulating hormone (or TSH), which signals your thyroid to make more thyroid hormone. Your thyroid gland then makes and releases the hormone directly into your bloodstream. Your pituitary gland then senses that there is just the right amount of thyroid hormone in your body.
