A goitre (pronounced goy-ter, sometimes spelt as 'goiter') is an enlarged thyroid gland. This gives you a lump at the front of your neck. Some people with a goitre have an underactive or overactive thyroid gland. This means that they make too much or too little thyroid hormone. There are various causes of goitre and treatment depends on the cause.
Glandular Epithelium - A gland is one or more cells that produce and secrete a specific product. The product is always a water-based fluid (aqueous) and usually contains proteins (the product is referred to as a secretion).

Thyroid Gland and Goitre:
The thyroid gland is a butterfly-shaped endocrine gland located in the front of the neck, just below the Adam's apple. It secretes hormones that are essential for the regulation of metabolism, growth, and development in the body. The enlargement of the thyroid gland is known as goitre.
Glandular Epithelium:
Glandular epithelium consists of cells that are specialized for secretion. These cells are responsible for producing and releasing substances such as hormones, enzymes, and mucus. Glandular epithelium is found in many organs and glands throughout the body, including the thyroid gland.
Explanation:
The thyroid gland is composed of follicles, which are small spherical structures filled with a protein-rich material called colloid. The follicular cells that line the follicles are responsible for the synthesis and secretion of thyroid hormones. These hormones include triiodothyronine (T3) and thyroxine (T4), which regulate the body's metabolism.
In goitre, the thyroid gland undergoes enlargement due to various reasons, such as iodine deficiency, autoimmune disorders, or certain medications. This enlargement results in swelling in the throat region, leading to a visible and palpable lump.
The involvement of glandular epithelium in goitre is due to the increased proliferation of follicular cells. The excessive growth and division of these cells cause the thyroid gland to enlarge and form a goitre. The increased activity of the glandular epithelium leads to the production and secretion of thyroid hormones, which may be either excessive or inadequate, depending on the underlying cause of the goitre.
Conclusion:
In goitre, the thyroid gland enlarges and results in swelling in the throat region. This condition involves the glandular epithelium, which shows increased proliferation and secretion of thyroid hormones. Understanding the role of glandular epithelium in goitre helps in comprehending the underlying mechanisms and potential treatment options for this disorder.
