What is thyroid

In this BIOLOGY video we will explain "What is the thyroid".

We continue with the endocrine system and we are going to know one of the most important peripheral glands: The thyroid. The thyroid is a gland in the shape of a butterfly or bow tie that we have in the lower part of the neck. Specifically below the larynx and above the sternum. In fact, trained doctors they have the ability to feel it the moment we swallow saliva. More or less would be in this area. This thyroid gland is a peripheral gland (meaning it is not part of the glands of the nervous system central) but depends directly on regulation by the central glands, that is, the hypothalamus and the hypophysis.

This thyroid gland you will specifically receive the hormone TSH (Thyroid-Stimulating Hormone) which you will do is the following: releases from the pituitary gland to the blood, travels and in the thyroid this hormone finds specific receptors for her. When this TSH binds to your thyroid receptors, the thyroid hormones. The thyroid does this in the following way: what it will do is capture the iodine that we ingest in the diet and it will bind it to a protein that is thyroglobulin. In this way, by joining iodine with trioglobulin we are going to manufacture the two types of hormones (T3 or T4).
