A thyroid nodule is a growth within the thyroid gland, which may or may not be felt by physical exam. Some nodules are only found incidentally on imaging of the thyroid. Thyroid nodules are very common and by age 60 almost one-half of all people will have a thyroid nodule.

Atlas Mountains: This mountain range is particularly in Northwestern Africa. They stretch all the way from Morocco on the Atlantic to Tunis on the Mediterranean Sea. The Great Sahara Desert: This desert is found behind the Atlas Mountain range to the south east. The Sahara's size and southerly location make it a particularly desert region.
