GENERAL HISTOLOGY

Detailed explanation-1: -A goiter (GOI-tur) is the irregular growth of the thyroid gland. The thyroid is a butterfly-shaped gland located at the base of the neck just below the Adam’s apple.

Detailed explanation-2: -Definition. A simple goiter is an enlargement of the thyroid gland. It is usually not a tumor or cancer.

Detailed explanation-3: -The most common cause of a goiter worldwide is a lack of iodine in the diet. In the United States, where iodized salt is readily available, goiters may be a result of the over-or underproduction of the thyroid hormone or the presence of nodules in the thyroid itself.

Detailed explanation-4: -Hashimoto’s thyroiditis is a more common cause of goiter formation in the US. This is an autoimmune condition in which there is destruction of the thyroid gland by one’s own immune system. As the gland becomes more damaged, it is less able to make adequate supplies of thyroid hormone.

Detailed explanation-5: -A goitre, or goiter, is a swelling in the neck resulting from an enlarged thyroid gland. A goitre can be associated with a thyroid that is not functioning properly. Worldwide, over 90% of goitre cases are caused by iodine deficiency. The term is from the Latin gutturia, meaning throat.
