The parathyroid gland, as with many glands throughout the body, consists of a simple cuboidal epithelium. Since it is an endocrine gland, these cells do not secrete their products onto the skin or into the lumen of ducts or tubular organs. Instead, they secrete their products into the surround connective tissue spaces containing capillaries, and the capillaries transport the product to the target tissue. We will come back to the thyroid and parathyroid glands at the end of the semester.
