Well, both Thyroid and Parathyroid glands are groups of Endocrine gland that is located in the base of the neck.
The thyroid glands are like a butterfly-shaped gland that lies in front of the trachea, just below the larynx. And its function is to make 2 thyroid hormones that regulate the way the body uses energy using iodine from food.
While the parathyroid glands are four tiny glands located just behind the thyroid gland. This gland produces a parathyroid hormone that helps control the amount of calcium in the blood.
