ANATOMY

Detailed explanation-1: -These glands, located behind the thyroid at the bottom of your neck, are about the size of a grain of rice. The parathyroid hormone produced by the thyroid glands helps maintain the right balance of calcium in the bloodstream and in tissues that depend on calcium for proper functioning.

Detailed explanation-2: -The 4 parathyroid glands are located near or attached to the back side of the thyroid gland and produce parathyroid hormone (PTH).

Detailed explanation-3: -Except in rare cases, parathyroid glands are in the neck behind the thyroid. Parathyroids are NOT related to the thyroid (except they are neighbors in the neck). The thyroid gland controls much of your body’s metabolism, but the parathyroid glands control body calcium.

Detailed explanation-4: -Parathyroid glands produce parathyroid hormone, which plays a key role in the regulation of calcium levels in the blood.

Detailed explanation-5: -Parathyroid hormone is secreted from four parathyroid glands, which are small glands in the neck, located behind the thyroid gland. Parathyroid hormone regulates calcium levels in the blood, largely by increasing the levels when they are too low.
