Question

In thyroid follicle, which type of epithelial tissue is present?

• A. Squamous
• B. Cuboidal
• C. Transitional
• D. Columnar

Answer 1

The correct option is B Cuboidal

Thyroid epithelial cells (also called as follicular cells or principal cells) are cells in the thyroid gland that are responsible for the production and secretion of thyroid hormones like thyroxine (T4) and triiodothyronine (T3). They are simple cuboidal epithelium and are arranged in spherical follicles surrounding colloid. The interior of one of these follicles is known as the follicular lumen. They have thyrotropin receptors on their surface, which respond to the thyroid-stimulating hormone. Calcitonin-producing parafollicular cells (C cells) can be found scattered along the basement membrane of the thyroid epithelium.

Thus, the correct answer is option B.
