==Parathyroids==

==Parathyroids==

There are usually two pairs of parathyroid glands. They measure about 0.5-1.0 mm in diameter and are located cranial to the [[Snake Cardiovascular System|heart]].  The caudal parathyroids are often associated with thymic tissue. The parathyroids play a very important role in calcium metabolism and accidental [[Lizard and Snake Surgery|surgical]] removal will result in hypocalcaemia and tetanic convulsions.
