MICROANATOMY

Detailed explanation-1: -Four small masses of epithelial tissue are embedded in the connective tissue capsule on the posterior surface of the thyroid glands. These are parathyroid glands, and they secrete parathyroid hormone or parathormone. Parathyroid hormone is the most important regulator of blood calcium levels.

Detailed explanation-2: -Anatomy Overview In its anatomic position, the thyroid gland lies posterior to the sternothyroid and sternohyoid muscles, wrapping around the cricoid cartilage and tracheal rings.

Detailed explanation-3: -The thyroid gland uses iodine from food to make two thyroid hormones that regulate the way the body uses energy. The parathyroid glands are four tiny glands located behind the thyroid gland. The parathyroid glands produce a substance (parathyroid hormone) that helps control the amount of calcium in the blood.

Detailed explanation-4: -The parathyroid glands are often directly adjacent to and/or located within the thyroid glands. The parathyroid glands are surrounded by a thin capsule, and separated into lobules via thin fibrous septa.

Detailed explanation-5: -Though they’re located near each other, the parathyroid glands are not related to the thyroid gland.
