Abstract
The parathyroid glands generally consist of four small oval disks with a diameter of 1 to 5 mm. The two largest parathyroids arise from the fourth branchial pouches and remain almost stationary during embryonic development, accounting for their final location at the cranial pole of the thyroid (Fig. 9–1). Two smaller parathyroids are usually located beneath the thyroid capsule, embedded at various depths near the caudal thyroid pole. They develop from the third branchial pouches in association with the thymus; migration with the descent of the thymus may give rise to ectopic parathyroid tissue.
