True statement regarding the Parathyroid glands is all Except

The inferior and superior parathyroid glands develop from the third and fouh pharyngeal pouches respectively. The thymus also develops from the third pouch. As it descends it takes the inferior parathyroid gland with it which explains why the inferior parathyroid which arises from the third pharyngeal pouch normally lies inferior to the superior gland. However, the inferior parathyroid may be found anywhere along this line of descent.
