How many parathyroid glands are there and where are they located?

Explanation:
Parathyroid glands consist of four tiny glands located on the posterior surface of the thyroid gland. There are two glands on the posterior surface of each thyroid lobe—one superior and one inferior—giving a total of four. This arrangement matches the description of having four glands, with one at the top and one at the bottom of each lobe. The other options are not correct because there aren’t only two glands, there isn’t a set of six embedded in the thyroid, and they aren’t located near the parotid glands. The parathyroids regulate calcium through parathyroid hormone.
