subbranchial glands, in biology, any Pharyngeal corpuscles that develop behind the fifth pair of branchial pockets in vertebrate embryos. In mammals, hypergill tissue has been integrated into parafollicular cells Parafollicular cells, also known as C cells, neuroendocrine cells in the thyroid. The main function of these cells is to secrete calcitonin. They are located near the thyroid follicles and in the connective tissue. https://en.wikipedia.org › wiki › Parafollicular_cell
