The Thyroid is one of the glands of the body's most important endocrine system, since it is this that controls the sensitivity of the body and the amount of hormone secretion that it takes advantage of. It is the thyroid, a checkpoint for the functioning of the other glands that respond to the bodily stimuli of the vertebrate. The living being to maintain a good relationship with its production of hormones, must have a regulator of these, since an excess of hormonal production can produce negative physical alterations among which are: external deformations, problems of sexual reproductionand assimilation of the nutrients that enter the system. Invertebrate animals lack this gland, their endocrine configuration is different, more independent.
In the case of human beings, the thyroid is located in the anterior part of the larynx, covering a considerable portion of the trachea, this privileged position allows it to fulfill extra functions in the body, such as keeping the trachea and the trachea lubricated. larynx with the secretion of its hormones simultaneously. The hormones secreted by the thyroid are thyroxine, triiodothyronine, and calcitonin, the first two destined for the production of hair, hair and maintenance of the hair follicle and the skin, as well as growth, development, temperature and heart rate. The last of these "Calcitonin" is incorporated into the equipment that works in the process ofcalcium homeostasis.
Many diseases are present in the thyroid gland that are related to excess production and wear and tear of the gland. In the case of " Hyperthyroidism " the gland increases the production of its hormones and therefore the body's energy expenditure is greater, which results in a serious deficit in the use of vitamins and nutrients that go to the body. Among the symptoms of hyperthyroidism are weight loss, heart conditions and many more that over time and the lack of correct treatment damage the patient's quality of life considerably. From a visual point of view, the gland grows, with an increase in volume in the front of the neck known as double chin.
