Final answer:
Hypertrophy of the submucosal glands is typically associated with chronic respiratory diseases like chronic bronchitis, not the thyroid disorders mentioned such as Graves disease or Hashimoto thyroiditis, where hypertrophy specifically refers to the thyroid's follicle cells.
Step-by-step explanation:
Hypertrophy of the submucosal glands is often seen in chronic respiratory diseases, such as chronic bronchitis. These glands are located in the submucosa, the layer of tissue beneath the mucous membrane, and their enlargement can lead to increased mucus production. While the question references hypertrophy of submucosal glands, the provided information describes goiter, which is an enlargement of the thyroid. However, it is important to clarify that goiter is a form of hypertrophy of the thyroid's follicle cells, which can occur in Graves disease and Hashimoto thyroiditis. In understanding this concept, it is significant to note that hypertrophic changes can occur in different organs, depending on the disease process.
