Nodular Goiter

	Nodular Goiter Nodular goiter is an enlarged thyroid gland with bumps (nodules) on it. It is associated with both high and low activity of the gland. * Toxic multinodular goitre Toxic multinodular goiter (TMNG), also known as multinodular toxic goiter (MNTG), is an active multinodular goiter associated with hyperthyroidism.

picture info	Thyroid Gland The thyroid, or thyroid gland, is an endocrine gland in vertebrates. In humans it is in the neck and consists of two connected lobe (anatomy), lobes. The lower two thirds of the lobes are connected by a thin band of Connective tissue, tissue called the thyroid isthmus. The thyroid is located at the front of the neck, below the Adam's apple. Microscopically, the functional unit of the thyroid gland is the spherical Thyroid follicular cell#Location, thyroid follicle, lined with thyroid follicular cell, follicular cells (thyrocytes), and occasional parafollicular cells that surround a follicular lumen, lumen containing colloid. The thyroid gland secretes three hormones: the two thyroid hormonestriiodothyronine, triiodothyronine (T3) and thyroid hormone, thyroxine (T4)and a peptide hormone, calcitonin. The thyroid hormones influence the basal metabolic rate, metabolic rate and protein biosynthesis, protein synthesis, and in children, growth and development. Calcitonin plays a role in ...

	Toxic Multinodular Goitre Toxic multinodular goiter (TMNG), also known as multinodular toxic goiter (MNTG), is an active multinodular goiter associated with hyperthyroidism. It is a common cause of hyperthyroidism in which there is excess production of thyroid hormones from functionally autonomous thyroid nodules, which do not require stimulation from thyroid stimulating hormone (TSH). Toxic multinodular goiter is the second most common cause of hyperthyroidism (after Graves' disease) in the developed world, whereas iodine deficiency is the most common cause of hypothyroidism in developing-world countries where the population is iodine-deficient. (Decreased iodine leads to decreased thyroid hormone.) However, iodine deficiency can cause goiter (thyroid enlargement); within a goitre, nodules can develop. Risk factors for toxic multinodular goiter include individuals over 60 years of age and being female. Signs and symptoms Symptoms of toxic multinodular goitre are similar to that of hyperthyroidism, inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
