What epithelial tissue secretes the hormones of the thyroid gland?
Most of the thyroid tissue consists of follicles lined by the follicular cells, which secrete the iodine-containing thyroid hormones.

Does the thyroid gland have epithelial tissue?
The thyroid gland contains two distinct populations of hormone secreting epithelial cells: thyroid follicular epithelium, and medullary (C) cells. The thyroid gland is surrounded by a thin fibrous capsule. The most prominent architectural feature of the thyroid gland are the thyroid follicles.
What is thyroid gland derived from?
The thyroid originates from two main structures: the primitive pharynx and the neural crest. The rudimentary lateral thyroid develops from neural crest cells, while the median thyroid, which forms the bulk of the gland, arises from the primitive pharynx.
Which two hormones are secreted by the thyroid gland?
The thyroid gland uses iodine from food to make two thyroid hormones: triiodothyronine (T3) and thyroxine (T4). It also stores these thyroid hormones and releases them as they are needed.
