AB Figure  59-1.  Normally,  there  are  four  parathyroid  glands,  situated  in  two  pairs  with  one  above  the  other  on  the  posterior  aspect  of  the  thyroid  gland.  Rarely,  the  parathyroids  may  be  found  inside  the  thyroid  gland  itself.  In  about  10%  of  individuals,  the  number  exceeds  four;  on  occasion,  there  are  fewer  than  four  glands.  The  inferior  pair  of  parathyroids,  which  arise  in  the  branchial  arch  that  also  gives  rise  to  the  thymus,  may  descend  into  the  mediastinum.
