Step 1
How does TSH travel to the thyroid gland?
Answer
Thyroid Stimulating Hormone (TSH) travels to the thyroid gland through the bloodstream.
Once TSH is released from the anterior pituitary gland in the brain, it enters the circulatory system. From there, it moves through the arteries and eventually reaches the thyroid gland located in the throat.
This transport mechanism ensures that TSH can effectively stimulate the thyroid gland to produce thyroxine, maintaining the hormonal balance necessary for regulating metabolism and growth.
